| 摘 要： | 通过建立大位移变形块体有限元模型,分析在水位骤降条件下重庆市涪陵地区某大型土质滑坡的稳定性.模拟结果表明,当水位骤降最大变形都集中在斜坡坡面较中后缘高陡坎处,坡体前缘变形较小,极大地影响边坡的稳定性;同时,分析了滑带土对边坡稳定性的影响.

| Abstract: | By a large displacement finite element model,the deformation of a large soil slope in Fuling,Chongqing was simulated,and its stability was analyzed when the water level before the slope sharply descended.The simulation results show that afer the water leverl is sharply descended the most deformation appears on the middle-back site of the slope.However,the deformation of the front sites is smaller,which greatly affects the stability of the slope.Furthermore,the influnce of soft soil between the slope bed and... |
