| 摘 要： | 采用非线性有限元法，对洗马河赛珠水电站大坝进行了静力和地震动力分析，讨论了大坝在加上地震作用后坝肩的位移，应力和点安全系数分布特性，并与静力工况作了比较。结果表明，地震作用下，坝肩位移与应力与静力工况相比都有明显增加，点安全系数也有很大程度降低。

| Abstract: | The nonlinear finite element method is used to study static force and seismic dynamic of the dam of Saizhu Hydropower Station on the Xima River.It discusses abutment displacement,distribution characteristics of stress and dot safety coefficient of the dam under seismic action,and compares the same with those under static force.Results show that abutment displacement and stress of the dam increase obviously under seismic action,whereas the dot safety coefficient drops greatly. |
