| 摘 要： | 为研究暴雨和库水位变化对三峡库区边坡变形和稳定的影响,选取重庆云阳县晒盐坝滑坡为研究对象.运用饱和非饱和渗流理论,采用有限元法,模拟该滑坡在暴雨和库水位升降中渗流场的变化,计算其稳定性系数.计算表明,库水位上升和下降中,该滑坡体的稳定性均先减小后增大.

| Abstract: | The landslide in Yunyang,Chongqing,is studied to explore about the influence of heavy rain and reservoir level on the stability of Three Gorges Reservoir slopes.Saturated-unsaturated seepage theory and finite element method are used to simulate the change of the seepage field to calculate stability coefficient.Calculations show that the stability first decreases and then increases no matter the level rises or falls. |

| Keywords: | Shaiyanba Landslide finite element seepage field stability |
