三峡船闸高边坡在地震作用下的稳定性分析

Stability analysis on high slopes of TGP lock under seismic action

采用有限元动力分析和改进的Sarma极限稳定分析程序对三峡船闸高边坡的动力特性、动态应力和动位移以及边坡的动力放大系数进行了计算分析 ,并对船闸高边坡在地震作用下的稳定性进行了计算。结果表明 ,在自重和地震作用下 ,边坡整体是稳定的。

A series of calculations, including mechanical parameters such as the dynamic characteristics, dynamic stress, dynamic displacement and dynamic magnification coefficient of the slope and the slope stability under seismic action, have been carried out using finite element method and the improved Sarma program. The result shows that the slopes of TGP lock are stable under the self-weight and earthquake load.
