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。
Geological conditions of slope stability and its influence factors are studied in air shaft site of Wangjialing coal mine. Based on the qualitative evaluation of slope stability by hemispherical projection method, the stability of typical slope sections in the entire site is analyzed under different operating condi tions by limiting equilibrium method （Sarma law） and finite element method, with the safety coefficients giv en. Results show that the outcomes of the two analyses are basically equivalent and the rationality of the methods is proved. The study may also offer reference for the evaluation and management of similar geotech nical slope problems.
