| 摘 要： | 采用GEO-SLOPE有限元计算软件对木竹坪滑坡在库水位上升、降雨、库水位上升和降雨共同作用下的地下水渗流场变化及稳定性进行了数值模拟计算。结果表明:不同工况条件下,地下水位线位置相差很大,但各工况下最可能滑动面的范围几乎一致;库水位上升和降雨共同作用对滑坡稳定性影响最为不利,其安全系数最小。

| Abstract: | GEO-SLOPE finite element software was adopted in numerical simulation calculation on variation and stability of groundwater seepage field under the effect of reservoir water level rise,rainfall,and the combination of reservoir water level rise and rainfall for Muzhuping landslide.The results show that there is a big difference in underground water level under different working conditions.Nevertheless,the slip surface ranges in different working conditions are almost the same.With the lowest safety factor,the combination of reservoir water level rise and rainfall poses the greatest threat to the stability of Muzhuping landslide. |
