Proposta per un maglev urbano. Lineamenti di un progetto di ricerca industriale per lo sviluppo di un sistema di trasporto innovativo

L'oggetto della proposta è un sistema di trasporto guidato di media potenzialità destinato alle aree metropolitane, basato sulla tecnologia della levitazione magnetica. Utilizza magneti permanenti ad alta energia per la sostentazione; un motore lineare sincrono per la propulsione; un dispositivo meccanico, o elettromagnetico, per stabilizzare la guida assicurata dagli stessi magneti della sostentazione. Il contenuto innovativo dell'oggetto non si limita alla parte non convenzionale (levitazione), ma investe tutto il sistema, poiché l'offerta industriale di un sistema destinato alle aree metropolitane è vincente solo se riferita ad un sistema completo (infrastruttura, veicoli, alimentazione, sistema di sicurezza, modello di esercizio, gestione, manutenzione, …). Si descrive inoltre la particolare soluzione inedita con abitacolo sospeso al di sotto dell'involucro tecnologico (comprendente magneti di sostentamento, motore lineare, sistema di guida, sospensione secondaria).

Studio geologico del comprensorio Centane-Via Panoramica (Isola di Procida, Golfo di Napoli)

E' stato eseguito uno studio geologico del comprensorio Centane-Panoramica (Isola di Procida, Golfo di Napoli) finalizzato alla determinazione delle caratteristiche tecniche dei terreni e della granulometria nelle aree lato mare che caratterizzano la falesia costiera tufacea tra Punta Pizzaco e Punta Solchiaro. Sono state eseguite prove penetrometriche dinamiche i cui risultati sono stati elaborati unitamente alle curve granulometriche dei terreni. I risultati ottenuti hanno consentito di definire il grado di dissesto geomorfologico e la natura dei terreni in aree sub-pianeggianti poste alla sommità della falesia costiera.

New morpho-bathymetric and tectono-stratigraphic data on Naples and Salerno gulfs (southern tyrrhenian sea, Italy) derived from bathymetric and seismic data analysis and integrated geological interpretation

New morpho-bathymetric and tectono-stratigraphic data on Naples and Salerno Gulfs, derived from bathymetric and seismic data analysis and integrated geologic interpretation are here presented. The CUBE(Combined Uncertainty Bathymetric Estimator) method has been applied to complex morphologies, such as the Capri continental slope and the related geological structures occurring in the Salerno Gulf.The bathymetric data analysis has been carried out for marine geological maps of the whole Campania continental margin at scales ranging from 1:25.000 to 1:10.000, including focused examples in Naples and Salerno Gulfs, Naples harbour, Capri and Ischia Islands and Salerno Valley. Seismic data analysis has allowed for the correlation of main morpho-structural lineaments recognized at a regional scale through multichannel profiles with morphological features cropping out at the sea bottom, evident from bathymetry.Main fault systems in the area have been represented on a tectonic sketch map, including the master fault located northwards to the Salerno Valley half graben. Some normal faults parallel to the master fault have been interpreted from the slope map derived from bathymetric data. A complex system of antithetic faults bound two morpho-structural highs located 20km to the south of the Capri Island. Some hints of compressional reactivation of normal faults in an extensional setting involving the whole Campania continental margin have been shown from seismic interpretation.

Interactions between Late Quaternary volcanic and sedimentary processes in the Naples Bay, Southern Tyrrhenian sea

The interactions between Late Quaternary volcanic and sedimentary processes in the Naples Bay, Southern Tyrrhenian sea, are here discussed through the results of the marine geological survey at the scale 1:25.000. The example of the geological map n. 465 “Isola di Procida”, herein presented, has put in evidence the stratigraphy of marine Quaternary deposits and related volcanic seismic units. The volcanic deposits cropping out in the Procida island have been explained as the result of eruptions of local eruptive centres. The geological survey carried out onshore indicates the occurrence of several pyroclastic units linked to the eruptive activity of the Ischian and Phlegrean volcanic complexes, interstratified with the products erupted by local volcanic centres. The occurrence in the pyroclastic sequences of Ischia and Procida islands of several marker horizons and their stratigraphic correlations have allowed to reconstruct the volcanological evolution of the two islands and the interactions with sedimentary processes at the scale of the whole Tyrrhenian margin. Four geological maps at the scale 1:25.000 covering the whole Naples Bay have been reconstructed based on the interpretation of marine geological and geophysical data. The stratigraphic relationships between the seismic units and the eruptive deposits have testified the activity of several monogenetic volcanic centers, whose products are interstratified with marine and continental deposits of the Late Quaternary depositional sequence.

Stratigraphic Architecture of Deep Sea Depositional Systems in the Southern Tyrrhenian Sea: Some Examples in the Ischia and Stromboli Volcanic Islands (Southern Italy)

The stratigraphic architecture of deep sea depositional systems has been discussed in detail. Some examples in Ischia and Stromboli volcanic islands (Southern Tyrrhenian sea, Italy) are here shown and discussed. The submarine slope and base of slope depositional systems represent a major component of marine and lacustrine basin fills, constituting primary targets for hydrocarbon exploration and development. The slope systems are characterized by seven seismic facies building blocks, including the turbiditic channel fills, the turbidite lobes, the sheet turbidites, the slide, slump and debris flow sheets, lobes and tongues, the fine-grained turbidite fills and sheets, the contourite drifts and finally, the hemipelagic drapes and fills. Sparker profiles offshore Ischia are presented. New seismo-stratigraphic evidence on buried volcanic structures and overlying Quaternary deposits of the eastern offshore of the Ischia Island are here discussed to highlight the implications on marine geophysics and volcanology. Regional seismic sections in the Ischia offshore across buried volcanic structures and debris avalanche and debris flow deposits are here presented and discussed. Deep sea depositional systems in the Ischia Island are well developed in correspondence to the Southern Ischia canyon system. The canyon system engraves a narrow continental shelf from Punta Imperatore to Punta San Pancrazio, being limited southwestwards from the relict volcanic edifice of the Ischia bank. While the eastern boundary of the canyon system is controlled by extensional tectonics, being limited from a NE-SW trending (counter-Apenninic) normal fault, its western boundary is controlled by volcanism, due to the growth of the Ischia volcanic bank. Submarine gravitational instabilities also acted in relationships to the canyon system, allowing for the individuation of large scale creeping at the sea bottom and hummocky deposits already interpreted as debris avalanche deposits. High resolution seismic data (Subbottom Chirp) coupled to high resolution Multibeam bathymetry collected in the frame of the Stromboli geophysical experiment aimed at recording seismic active data and tomography of the Stromboli Island are here presented. A new detailed swath bathymetry of Stromboli Island is here shown and discussed to reconstruct an up-to-date morpho-bathymetry and marine geology of the area, compared to volcanologic setting of the Aeolian volcanic complex. The Stromboli DEM gives information about the submerged structure of the volcano, particularly about the volcano-tectonic and gravitational processes involving the submarine flanks of the edifice. Several seismic units have been identified around the volcanic edifice and interpreted as volcanic acoustic basement pertaining to the volcano and overlying slide chaotic bodies emplaced during its complex volcano-tectonic evolution. They are related to the eruptive activity of Stromboli, mainly poliphasic and to regional geological processes involving the geology of the Aeolian Arc.

Studio geologico-geomorfologico per la soluzione di problematiche tecnico-applicative nelle località Terra Murata (borgo medievale e costone lato Marina Corricella) e Centane-Panoramica (Isola di Procida, Golfo di Napoli)

Nel presente rapporto tecnico viene illustrato uno studio del dissesto geomorfologico in due aree selezionate dell’Isola di Procida, rispettivamente ubicate nella zona storica di Procida (borgo medievale di Terra Murata lungo la Via Salita Castello-altezza Via S. Domenico) e nell’area costiera che raccorda Punta Pizzaco con Punta Solchiaro (comprensorio Centane-Panoramica). In generale le finalità del rapporto tecnico sono quelle di fornire un inquadramento di queste due zone da un punto di vista geologico, che si differenziano negli aspetti particolari. Infatti, nella zona di Terra Murata, sia nella zona alta del borgo medievale (piazzale oltre le mura) che lungo il costone tufaceo antistante la Marina Corricella (salita Castello all’altezza di Via S. Domenico) sono documentate copiose perdite d’acqua attraverso i terreni vulcanici di natura tufacea e pozzolanica che affiorano nell’area. Tali perdite d’acqua attraverso i terreni interessano anche numerose abitazioni, creando disagi che rendono necessario l’ulteriore accertamento tecnico al fine di individuare, anche tentativamente, le cause di tali dissesti e di proporre soluzioni tecnicamente soddisfacenti a tali problematiche attraverso uno studio approfondito.
