摘要
Abstract
In order to understand the stability of the end slope in Weijiamao Open-pit Coal Mine,the article selects the typical engineering geological section of the end slope in Weijiamao Open-pit Coal Mine,and obtains the recommended values of physical and mechanical indexes of rock and soil mass for slope stability analysis by comprehensive analysis.The article analyzes the deformation and failure mode of the end slope by numerical simulation method,and calculates the stability coefficient of the end slope by Bishop method.The results show that the potential deformation and failure mode of the end slope is the whole or multi-step combined arc shear failure mode.The stability coefficient of the end slope is greater than 1.20,and the end slope is stable as a whole.关键词
