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。 Based on the seepage theory of unsaturated soil, Geo-studio numerical simulation software was used to simulate the saturated and unsaturated soils produced by the water level rise and fall after the reservoir was impounded, and to evaluate the stability of the slope after the reservoir water level rising and falling influences. The results show that the landslide is in a stable state in its natural state, instability will occur after water storage, and measures must be taken before water storage.
