| 摘要: |
| 采用有限元边坡稳定分析方法，计算了正弦波动力作用下模型坝坝体最危险滑裂面和相应的最小安全系数，得到最危险滑裂面和最小安全系数的时间过程。分析了静、动力作用下模型坝边坡最危险滑裂面与试验破坏面三者之间的关系。 |

| Finite element analysis for slope stability of dam model under action of sinusoidal wave |
|
|
| Abstract: |
| The limit sliding surfaces and the corresponding minimum safety coefficients of a dam model under sinusoidal wave action are calculated by using finite element method, and their time processes are thus obtained. The relationship between the limit sliding surfaces under static or dynamic loads and the experimental failure surface of the dam model is also analyzed. |
| Key words: sinusoidal wave,dynamic response process,finite element method,limit sliding surface,minimum safety coefficient,slope stability |
