摘要

针对王家岭煤矿风井场地边坡稳定性问题

调查分析了该边坡的工程地质条件和影响边坡稳定性的因素。在用赤平投影法对边坡稳定性进行定性评价的基础上

采用极限平衡法(Sarma法)和有限元法对整个场地典型边坡剖面进行了不同工况条件下的稳定性分析

并给出了安全稳定系数。结果表明

二者分析结果基本一致

验证了所用方法的合理性。对类似工程问题的评价、治理有一定的借鉴和指导意义。

Abstract

Geological conditions of slope stability and its influence factors are studied in air shaft site ofWangjialing coal mine.Based on the qualitative evaluation of slope stability by hemispherical projectionmethod

the stability of typical slope sections in the entire site is analyzed under different operating conditions by limiting equilibrium method(Sarma law)and finite element method

with the safety coefficients given.Results show that the outcomes of the two analyses are basically equivalent and the rationality of themethods is proved.The study may also offer reference for the evaluation and management of similar geotechnical slope problems.
