摘要
基于现场工程地质勘察和岩石力学试验,建立数值模拟计算模型,从应力、位移、塑性区变化等方面进行边坡稳定性分析。模拟分析结果表明:由于岩体剪切破坏造成坡脚贯通产生滑移面,在楔形破坏作用下可能产生滑坡。因此应加强边坡坡脚治理,必要时进行削坡卸载。
Based on the field engineering geological survey and the rock mechanics test, the numerical simulation model was established, and the slope stability analysis was carried out from the aspects of stress, displacement and the change of plastic zone. The simulation results show that the slip surface is generated due to the shear failure of the rock mass and the landslide may occur under wedge failure. Therefore, it is necessary to strengthen the slope slope footing, if necessary, to carry out slope unloadingn.
