库水位下降及极端降雨作用下白家包滑坡的稳定性演化
Stability Evolution of Baijiabao Landslide under Effects of Reservoir Water Level Decline and Extreme Rainfall
摘要
Abstract
To study the response of the seepage field and stability of a landslide under the combined effects of reser-voir water level decline and rainfall,this paper examines the Baijiabao landslide in the Three Gorges Reservoir Are-a.Using Geo-studio finite element analysis software,the seepage field of the landslide was simulated under six con-ditions with reservoir water level declining at rates of 0.6 m/d,1.0 m/d,and 1.2 m/d,combined with extreme rainfall with a 50-year return period,and the stability coefficient was calculated.Results show that as the reservoir water level decreases,the groundwater level profile exhibits convex and concave patterns,while the stability coeffi-cient initially decreases and then increases.When extreme rainfall is superimposed,the stability of the landslide shows more significant changes as the rate of reservoir water level decline increases.关键词
