苏南某矿坑边坡稳定性分析

Stability analysis of a mine slope in southern jiangsu

某苏南矿坑,由于多年开采,宕口直径约400m,深约70m,稳定性极差,崩塌、滑坡时有发生,给周边人民造成了极大的安全隐患,因此,对研究区展开工程地质研究很有必要。本文从对研究区的边坡稳定性方面进行分析,对研究区各分区的破坏模式作了详细的分析以及对比,在研究区中选取代表性剖面,对其进行稳定性评价,对各分区边坡稳定性有了定量、定性的评价结果,为后期治理方案提供了可靠的依据。

A mine in southern Jiangsu,due to years of mining,down the diameter of about 400m,about 70m deep,poor stability,collapse,landslides occur from time to time,to the surrounding people caused a great potential safety,therefore,it is necessary to carry out engineering geology research in the research area.Based on the analysis of slope stability in the study area,the failure modes of each partition in the studied area has made the detailed analysis and comparison,choose representative section in the study area,on the stability evaluation,slope stability of each division has a quantitative and qualitative evaluation results,for the late management program provides a reliable basis.
