| 摘 要： | 基于完全非线性的动力分析方法，对边坡地震作用下的稳定性开展研究。分析得出：地震作用下，边坡最大永久位移主要集中于坡面；对于垂直方向上布置的关键点，随高程增加，位移时程表现为“放大”，加速度时程呈现“放大”和“滞后”；对于水平方向布置的关键点，由坡内向外，位移时程表现为“放大”，加速度时程却出现“衰减”和“同步”。研究结果有助于进一步揭示边坡在地震作用下的失稳机制。

| Abstract: | Based on fully non-linear dynamic analysis methods,slope stability under earthquakes was analyzed.It was shown that: Under earthquakes effect,the maximum permanent displacement focused mainly on the surface of the slope;For the vertical key points,with the elevation increasing,the displacement-term expressed as zoom,the acceleration-term showed zoom and lag;For the horizontal key points,from inside to outside,the displacement-term performed as zoom,the acceleration-term showed decay and synchronization.The ... |
