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。
Based on the engineering geological data of a Yalong River slope, this paper analyzes the failure mechanism and failure mode of the slope, and uses the numerical method to evaluate the stability of the collapse body. The numerical calculation relies on FLAC3D software to calculate and analyze. Firstly, the grid model of slope is established in ANSYS, and then the model is imported into FLAC3D to calculate. The conclusion is drawn that the stability of the collapse body is less affected by water storage , The safety factor is lower than the natural state is also lower, and the impact of seismic conditions on the stability of the slope is very significant, the slope may have a total destruction.
