摘要
基于非饱和土渗流理论,运用Geo-studio有限元数值模拟软件,对水库蓄水后水位升降产生的饱和土及非饱和土进行数值模拟,评价水库蓄水后水位升降对该边坡的稳定性影响。结果表明,滑坡在天然状态处于稳定状态;在蓄水后将发生失稳,蓄水前必须采取治理措施。
The unsaturated flow theory and the Geo studio finite element numerical simulation software are used to simulate the saturated soil and unsaturated soil caused by water level fluctuation. The evaluation results show that the landslide is stable in natural condition and loses its stability after the reservoir being impounded with water.
