边坡动力响应分析及应用研究

As a marginal subject, dynamic responses of slopes is not only an important problem of engineering geology (Geotechnical problem), but also of other subjects such as seismology, geophysics, seismic engineering and engineering seismic and so on. Owning to the gulf between different subjects, it is arduous to study dynamic responses of slopes and the study is far from ripeness. Studying on the dynamic responses of slopes is very important in theories as well as practices. Supported by hundreds of bibliographies, this paper systemically details the development process of this subject, introduces main means to analyze this subject, and then gives brief remarks to each means respectively. Engineering geology qualitative analysis is the base of slopes dynamic responses study. Because of complexity of geological conditions, engineering geology qualitative analysis is very important in slopes stability study, especially to rock slopes with complex engineering geology conditions. Based on research fruits of forerunners, this paper summarizes factors influencing slopes dynamic stability into five aspects as geology background, stratums, rock mass structure, and topography as well as hydrogeology condition. Based on rock mass structure controlling theory, engineering geology model of the slope is grouped into two typical classes, one is model with obvious controlling discontinuities, which includes horizontal bedded slope, bedding slope, anti-dip slope, slide as well as slope with base rock and weathered crust; the other is model without obvious controlling discontinuities, which includes homogeneous soil slope, joint rock mass slope. Study on slope failure mechanism under dynamic force, the paper concludes that there are two effects will appear in slope during strong earthquake, one is earthquake inertia force, the other is ultra pore pressure buildup. The two effects lead to failure of the slope. To different types of slope failure, the intensity of two effects acting on the slope is different too. To plastic flow failure, pore pressure buildup is dominant; to falling rock failure and toppling failure, earthquake inertia force is dominant in general. This paper briefly introduces the principle of Lagrangian element method. Through a lot of numerical simulations with FLAC3D, the paper comprehensively studies dynamic responses of slopes, and finds that: if the slope is low, displacement, velocity and acceleration are linear enlarging with elevation increasing in vertical direction; if the slope is high enough, displacement, velocity and acceleration are not linear with elevation any more, on the other hand, they fluctuate with certain rhythm. At the same time, the rhythm appears in the horizontal direction in the certain area near surface of the slope. The distribution form of isoline of displacement, velocity and acceleration in the section of the slope is remarkably affected by the slope angle. In the certain area near the slope surface, isoline of displacement, velocity and acceleration is parallel to the surface of the slope, in the mean time, the strike direction of the extreraum area is parallel to the surface of the slope too. Beyond this area, the isoline direction and the strike direction of the extremum area turn to horizontal with invariable distance. But the rhythm appearing or not has nothing to with the slope angle. The paper defines the high slope effect and the low slope effect of slopes dynamic responses, discusses the threshold height H^t of the dynamic high slope effect, and finds that AW is proportional to square root of the dynamic elastic moduli El P , at the same time, it is proportional to period Tof the dynamic input. Thus, the discriminant of H^t is achieved. The discriminant can tell us that to a slope, if its height is larger than one fifth of the wavelength, its response regular will be the dynamic high slope effect; on the other hand, its response regular will be the dynamic low slope effect. Based on these, the discriminant of different slopes taking on same response under the same dynamic input is put forward in this paper. At the same time, the paper studies distribution law of the rhythm extremum point of displacement, velocity and acceleration, and finds that there exists relationship of N = int among the slope height H, the number of the rhythm extremum VHlhro) point N and ffthre- Furthermore, the paper points out that if N^l, the response of the slope will be dynamic high slope effect; \fNof the slope will be dynamic low slope effect, and the distance of the two adjacent extremum points equals to //,/,",. At the same time, the paper finds that the distance of two adjacent extremum districts near the slope surface is H,hn too. In chaptet 5, based on residual pushing force model as well as pore pressure model of Martin-Finn-Seed, a method for estimating the permanent displacement of the slide is put forward in this paper, and then put it into dynamic analysis of the left abutment slope of Jinping hydropower station. The forecasting result is almost coincided with numerical simulation result. The Jinping hydropower station, located at the middle stream of Yalongjiang River and the west side of Jinpingdahewan, is the highest double-curvature arch dam planned in building in the world. However, deep fractures are well developed at the left abutment slope, so stability of the slope is a key engineering geological problem. The paper studies the dynamic stability of the slope. In the analysis, considering regional geology and regional seismology of the slope, combining with characteristics of the slope as well as the scale of the project, PGA(peak ground acceleration) of the site is decided (about 197.1cm/s2) by engineering seismology, and then the seismic input used in the slope dynamic analysis is determined. Comprehensive studies are carried out on the slope, especially to its deep fractures, and then the paper concludes that the deep fractures of slope are the result of the combination unloading effect of gravity and tectonic stress. At the same time, the failure model of the slope under dynamic input is attained. Based on these, the stability is comprehensively studied for section IV-IV with numerical simulation method as well as method putting forward in chapter 5. At last, the paper concludes that under dynamic input, the section will slide along fault f9, some deep fractures and fault/5 with certain permanent displacement, and this must be taken into consideration in the engineering.

Nie tylko Dzierżon: wprowadzenie do bibliografii piśmiennictwa pszczelniczego na Śląsku

Zadaniem artykułu jest ukazanie dorobku piśmiennictwa pszczelniczego na Śląsku. Pretekstem do poruszenia tego tematu jest przypadająca w 2011 roku dwusetna rocznica urodzin wybitnego pszczelarza Jana Dzierżona. Osoba i dokonania najsłynniejszego chyba w świecie Ślązaka do tego stopnia zdominowały historię pszczelarstwa tego regionu, że właściwie bardzo niewiele mówi się o dorobku innych działających aktywnie śląskich pszczelarzach praktykach i publicystach. Tymczasem dorobek ten jest imponujący. W części pierwszej artykułu przypomniano Nickela Jacoba ze Szprotawy, autora pierwszej wydanej na Śląsku książki pszczelarskiej, uznanego jednocześnie za ojca niemieckiej bibliografii pszczelarskiej. Wśród pionierów niemieckiej literatury fachowej dotyczącej pszczół znajduje się też Johann Coler ze Złotoryi. W XVIII wieku swą działalność praktyczną i publicystyczną w znacznej mierze związali ze Śląskiem Łużyczanin Adam Gottlieb Schirach i Niemiec Johann Riem. W dziełach innych autorów z zakresu gospodarstwa wiejskiego pojawiają się również fragmenty poświęcone pszczelarstwu. Dorobek swych poprzedników wzbogacił i swą działalnością rozsławił śląskie pszczelarstwo ksiądz dr Jan Dzierżon, odkrywca partenogenezy, konstruktor nowoczesnego ula, autor licznych publikacji. „Księciu pszczół” poświęcona została druga część artykułu. Przedstawiono w niej pokrótce jego życie i działalność, dzieje walki o uznanie teorii partenogenezy, ogromny dorobek publicystyczny. Wskazano jednocześnie na brak opracowania pełnej bibliografii podmiotowej. Dzierżon był wydawcą jednego z pierwszych na Śląsku czasopism pszczelarskich. Dorobek śląskiego czasopiśmiennictwa pszczelarskiego jest bogaty i dziwi fakt, że właściwie w bardzo małym dotychczas stopniu został poznany. Część trzecią poświęcono niemieckim i polskim czasopismom pszczelarskim wydawanym na Śląsku. Uwzględniono tutaj tytuły samoistne oraz dodatki. W podsumowaniu wykazano, że we wszystkich obszarach bibliografia piśmiennictwa śląskiego wymaga kompleksowego rozpoznania. Stan opracowania piśmiennictwa pszczelarskiego na Śląsku stanowi w pewnej mierze odbicie stanu bibliografii tego zagadnienia na ziemiach polskich.

Adaptation to the Environment: Changes in Initial Projects in Ottoman Shephardic Press

The origins of Sephardic press date back to the mid-20th century, when the influence of the Western world spread across the Sephardim communities of the East. The content of these newspapers was diverse: pieces of general interest, but also scientific, literary and humorous works, with various political orientations. These papers were published in different languages, writing styles and alphabets. Those to be analysed here, however, were published in aljamiado Judeo-Spanish: three papers from Smyrna and one from Salonica. Throughout this work we will focus on the different obstacles and difficulties the editors and publishers of this Ottoman Sephardic press had to face to bring their publications to light.

Nanoparticles based Permeable Reactive Barriers as an Eco-efficient Technology for nitrate remediation in soil and groundwater

The need to increase agricultural yield led, among others, to an increase in the consumption of nitrogen based fertilizers. As a consequence, there are excessive concentrations of nitrates, the most abundant of the reactive nitrogen (Nr) species, in several areas of the world. The demographic changes and projected population growth for the next decades, and the economic shifts which are already shaping the near future are powerful drivers for a further intensification in the use of fertilizers, with a predicted increase of the nitrogen loads in soils. Nitrate easily diffuses in the subsurface environments, portraying high mobility in soils. Moreover, the presence of high nitrate loads in water has the potential to cause an array of health dysfunctions, such as methemoglobinemia and several cancers. Permeable Reactive Barriers (PRB) placed strategically relatively to the nitrate source constitute an effective technology to tackle nitrate pollution. Ergo, PRB avoid various adverse impacts resulting from the displacement of reactive nitrogen downstream along water bodies. A four stages literature review was carried out in 34 databases. Initially, a set of pertinent key words were identified to perform the initial databases searches. Then, the synonyms of those initial key words were used to carry out a second set of databases searches. The third stage comprised the identification of other additional relevant terms from the research papers identified in the previous two stages. Again, databases searches were performed with this third set of key words. The final step consisted of the identification of relevant papers from the bibliography of the relevant papers identified in the previous three stages of the literature review process. The set of papers identified as relevant for in-depth analysis were assessed considering a set of relevant characterization variables.

Industrial Adjustment: Context, Causes, Impacts and Methods for Analysis

Adjustement is an ongoing process by which factors of reallocated to equalize their returns in different uses. Adjustment occurs though market mechanisms or intrafirm reallocation of resources as a result of changes in terms of trade, government policies, resource availability, technological change, etc. These changes alter production opportunities and production, transaction and information costs, and consequently modify production functions, organizational design, etc. In this paper we define adjustment (section 2); review empirical estimates of the extent of adjustment in Canada and abroad (section 3); review selected features of the trade policy and adjustment context of relevance for policy formulation among which: slow growth, a shift to services, a shift to the Pacific Rim, the internationalization of production, investment distribution communications the growing use of NTB's, changes in foreign direct investment patterns, intrafirm and intraindustry trade, interregional trade flows, differences in micro economic adjustment processes of adjustment as between subsidiaries and Canadian companies (section 4); examine methodologies and results of studies of the impact of trade liberalization on jobs (section 5); and review the R. Harris general equilibrium model (section 6). Our conclusion emphasizes the importance of harmonizing commercial and domestic policies dealing with adjustment (section 7). We close with a bibliography of relevant publications.

MCDA: análise de decisão multicritério como ferramenta de avaliação de instalações portuárias: o caso dos terminais de contêineres brasileiros

Este trabalho busca avaliar, com suporte da metodologia MCDA - análise de decisão multicritério, os terminais de contêineres brasileiros quanto a suas potencialidades como vetores de crescimento sustentado da economia, no médio e longo prazo, para priorização de investimentos públicos e privados. O trabalho se consubstancia em um levantamento bibliográfico do tema decisório, que lhe serve de base, seguido de um estudo do tema portuário, a fim de levantar os fatores que tornam viável o florescimento e desenvolvimento de um sítio portuário, além de buscar tendências do setor de contêineres no Brasil. Após estas etapas, foi desenvolvido uma modelagem para o problema de avaliação dos terminais, com ajuda do software Expert Choice. Os resultados obtidos apontam para uma alteração sensível de paradigma no panorama portuário nacional em um cenário futuro. Portos que hoje se localizam na parte superior da lista de movimentação de contêineres, à frente nas estatísticas, podem não ter para onde se expandir, enquanto outros, que se encontram menos pujantes, podem florescer nas próximas décadas, devido às características de cada sítio portuário. As mais relevantes foram selecionadas como critérios do modelo desenvolvido, são eles: águas abrigadas, retroáreas, acessos terrestres e marítimos, equacionamento de questões ambientais, localização estratégica, vocação regional, extensão de cais e áreas de expansão. Entre as conclusões deste estudo, pode-se citar: 1 - O Porto de Santos, tradicional líder do ranking nacional em movimentação de contêineres, deve se manter entre os primeiros, graças à sua proximidade com o principal centro econômico e industrial nacional, a região da grande São Paulo, embora esteja com sua capacidade perto do limite operacional, conta com áreas de expansão, como o projeto Barnabé-Bagres. 2 - Outro porto que se destacou na classificação final foi o de Itaguaí, já hoje com movimentação crescente e enorme potencial de crescimento na área de contêineres. Possui excelente condição de águas abrigadas, boa localização estratégica, entre Rio de Janeiro e São Paulo, dois pólos econômicos fortes, com influência decisiva no cenário nacional, e que dispõe de consistente plano de expansão, especialmente relacionado ao aumento de contêineres.

A contribuição da asstênia técnica no desenvolvimento desenvolvimento de projetos de assentamento no estado do Rio Grande do Norte

The public policies must have as their aimed the primordial at improving quality of life of families of a given population, however, its performance must be constantly monitored and evaluated scoped to ascertain whether these policies are reaching those goals. This work consisted in search of bibliographies and analysis that addressed the historical evolution of the debate on the subject of agrarian reform in Brazil as public policy and on the policy of technical assistance and rural extension, and collecting data in loco, in order to assess whether the actions implemented under this latter contribute to improvements in local development of settlements projects (PA) land reform in the state of Rio Grande do Norte (RN), this given the constant presented criticisms regarding their effectiveness, considering that it is difficult to empirically differentiate settlements they received of those who did not receive the technical assistance services. In this way, was held the data collection for comparison of characteristics (social organization, relationship with the local environment, form of producing and evaluation of technical assistance services) of two settlements in RN, being one you have received the technical assistance services and another who has not had access to these services in the past five years, at least, to confirm whether those who had access to the above services presents best features of social organization and the relationship with the local environment, mainly, which was confirmed in the results obtained, which still demonstrated that no significant differences on the forma to produce and of commercialization in PA studied. It was also found that the problems faced by families settled in PA studied resemble those seen verified in many other Brazilian states, especially as to how to use natural resources in the areas of land reform and the instability of the availability of technical assistance services. Should be guaranteed at continuity and universality of technical assistance services to settlements, seeking a higher focus on productive issues, which provide the income necessary for families settled can have a better quality of life
