摘要

水库蓄水将显著改变库岸的水文地质条件，进而影响滑坡的稳定状态。以鄂西南某水库为例，阐述了库水位对滑坡稳定性影响的一般规律，并采用剩余推力法计算分析了滑带土抗剪参数、库水位变化和地下水疏干系数对库岸滑坡的影响。在此基础上，对蓄水后库岸滑坡的变形模式进行了模拟分析。研究表明，水库蓄水不仅使滑坡稳定性发生变化，滑坡的变形模式也将由推移式转变为牵引式。

Abstract

After water impounding

hydrogeological condition in the reservoir area varies obviously and landslide stability is affected. Taking a reservoir in Southwest Hubei for example

general law of influence of reservoir water level on landslide stability is discussed. By use of push method

anti-shearing parameters

affection by water level variation and drainage factor is analyzed. Additionally

numerical simulation are adopted to analyze its sliding mode. It is showm that reservoir water impounding not noly influences landslide stability but also the failure mode

i.e.the that is to say

push mode will be substituted by drag mode.
