摘要
在简述三峡工程库区奉节段的地质和水文地质条件的基础上,对库段内将会出现的地下水渗流场变化进行了三维模拟,并对库岸斜坡在蓄水过程中稳定性的变化进行了分析和论证。参与计算的4条库岸斜坡地质剖面中,除9-9/剖面(老房子滑坡)有可能失稳外,其它岸坡不存在整体失稳的可能。
On the basis of the brief exposition of the geologic and hydrogeologic situations in Fengjie sector of Three-gorge hydraulic project, Yangtze River, the article simulate the dynamical change of the groundwater level in Fengjie sector, analyses and demonstrates the stability of the slope in the sector during the process of storing water. The results show that all the slopes will be stable except Laofangzi landslide.
