摘要

该文结合雅砻江某边坡现场调查的工程地质资料,分析其破坏机制及破坏形式,利用数值计算方法对崩塌体进行稳定性评价。数值计算依赖FLAC3D软件进行计算分析,首先在ANSYS中建立边坡的网格模型,再将模型导入FLAC3D进行计算,得出了崩塌体稳定性的相关结论:蓄水对于崩塌体的稳定影响较小,安全系数较自然状态下降低幅度也较低,而地震工况对于边坡的稳定性影响非常显著,边坡有可能出现整体性的破坏。
Combined with the engineering geological data in field investigation of a slope in Yalong Jiang,the failure mechanism and form is studied in this paper.Landslide has been conducted for numerical simulation by using the software FLAC3D.Firstly,the grid model is built by the software ANSYS,secondly,the grid model is imported into FLAC3D,finally,the related conclusions after calculating are obtained that,it has little effect on the stability of landslide in the water-storing state,and the safety factors decrease lower than that in the natural state.However,the stability of slope would further significant deteriorate in the condition of earthquake,and the slope may be destroyed entirely.
