【摘要】 本文利用Geo-Studio软件对库水位作用下BZM滑坡的渗流场及稳定性进行了模拟分析。分析结果表明:①BZM滑坡中前部地下水位受库水位变动的影响较大,库水位的波动会直接影响地下水位的波动,且地下水位有延迟效应。地下水位线随库水位下降时,其呈现直线递增的趋势,且增大的速率先快后慢。②库水位波动对BZM滑坡稳定系数有较大影响,具体为:库水位下降时,BZM滑坡稳定系数也会逐减小,表现出典型的动水压力型滑坡特征。库水位下降速率大时,稳定系数下降速率相对较大。更多还原

【Abstract】 This paper uses Geo-Studio software to simulate the seepage field and stability of BZM landslide under reservoir water level.The analysis results show that:①the front groundwater level in the BZM landslide is greatly affected by the fluctuation of the reservoir water level. The fluctuation of the reservoir water level will directly affect the fluctuation of the groundwater level, and the groundwater level has a delay effect. When the groundwater level line decreases with the reservoir water level, it tends to increase linearly, and the rate of increase is faster and slower.② Reservoir water level fluctuation has a great influence on the stability coefficient of BZM landslide. Specifically,when the reservoir water level decreases, the stability coefficient of BZM landslide will also decrease, showing the characteristics of typical hydrodynamic pressure landslide. When the reservoir water level decline rate is large, the rate of decline of the stability coefficient is relatively large.更多还原
