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FLAC 3D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FLAC 3D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 numeri-cal simulation by using the software FLAC 3D .Firstly, the grid model is built by the software ANSYS , sec-ondly, the grid model is imported into FLAC 3D , finally, the related conclusions after calculating are ob-tained 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 de-teriorate in the condition of earthquake, and the slope may be destroyed entirely.
