摘要
采用有效应力非线性有限元法对埃塞俄比亚Kesem粘土心墙土石坝进行了地震反应分析。得到该坝在地震作用下坝体的加速度反应和应力反应,根据坝坡残余变形及坝坡的动力稳定性等进行了抗震评价。
The dynamic response of the Kesem Clay-Core Embankment in Ethiopia under seismic load action is investigated with nonlinear effective-stress FEM;the maximum seismic response acceleration and stresses are acquired;in accordance with the residual deformation and dynamic stability of the embankment slope,the aseismic safety of the embankment is evaluated.
