| 摘 要： | 以三峡库区某边坡工程实例为背景,选用拟静力法对地震荷载进行模拟,采用有限单元法对库岸边坡在地震和库水变化综合作用和仅在库水变化作用2种工况条件下的位移和等效塑性应变进行了计算,通过对2种工况计算结果进行对比,分析了地震作用对库岸边坡稳定性的影响. |

| Abstract: | Taking a certain bank stope in Three Gorges Reservoir area as background,the pseudo-static method is used to simulate earthquake load.The displacement field and equivalent plastic strain of a bank slope in Three Gorges Reservoir area under earthquake and water level fluctuation and under only water level fluctuation are calculated by finite element method.Through the comparison of results under two conditions,the influence of earthquate on bank slope stability is studied. |
| Keywords: | pseudo-static method earthquake water level fluctuation stability |
