潘洛铁矿滑坡特征分析及防治

分析了潘洛铁矿露天矿滑坡灾害发生发展的特征,得出该滑坡是一个动态的、多层次的复合型滑坡;找出了影响该边坡稳定的主要因素是大气降雨和采矿切割坡脚;根据这些影响因素和滑坡发展变化规律,提出了科学合理的滑坡治理方案,即动态的综合治理方案.经现场实施后,通过滑坡监测数据表明,该滑坡得到了彻底根治.

A Dynamic Comprehensive Method for Landslide Control

A slope failure is developed due to progressive external loads and deteriorations of slope geomaterials, thus forming a progressive and dynamic development and occurrence of landslides. Site geological properties and other active factors such as hydrodynamic load and human activities are complex and usually unknown, thus this dynamic development and occurrence of landslides can only be understood through the progressive accumulation of knowledge on the landslides. For such a progressive process, this paper proposes a dynamic comprehensive control method for landslide control. This control method takes full advantage of updated monitoring data and site investigations of landslides, and emphasizes the implementation of possible measures for landslide control at reasonable stages and in different groups. These measures are to prevent the occurrence of a landslide disaster. As a case study, a landslide project at the Panluo open-pit iron mine is analyzed to illustrate this dynamic comprehensive control method.
