| 摘 要： | 三峡水库蓄水后,库水位涨落和降雨入渗是导致滑坡的主要因素。本文以秭归县下土地岭滑坡为例,在一个水文年内根据库区水位调控方案并考虑库区降雨情况,运用非饱和土力学的渗流和抗剪强度理论,对滑坡稳定性进行了分析,得出在库水位涨落和降雨条件下滑坡渗流和稳定性的变化规律,对库区滑坡稳定性评价和治理有一定的指导作用。

| Abstract: | After the Three Gorges Reservoir impounding,reservoir water level fluctuation and rainfall infiltration have become the major factors that affect the stability of landslide.Taking Xiatudiling landslide in Zigui County as an example,according to the water level operation options,considering the case of rainfall in a hydrological year in the Three Gorges Reservoir region,the variation of landslide stability is analyzed,based on the theory of seepage and shear strength of unsaturated soils.Changes of landslide stability and infiltration are obtained with reservoir water level fluctuation and rainfall.It has some directive values for stability evaluation and treatment of landslide. |

| Keywords: | reservoir water level fluctuation rainfall shear strength of unsaturated soils landslide stability |
