地震荷载下土石坝变形分析

Deformation analysis of earth-rock dam under earthquake loading

土石坝在地震荷载下的内部应力应变变化越来越受到重视,针对此问题以辽宁省抚顺市清原县小孤家水库土石坝为例,使用ABAQUS软件,模拟其在地震荷载下的应力应变变化情况,分析计算结果,最后得出该土石坝在此荷载条件下x方向位移和永久变形分布图及加速度变化曲线图,其结果与理论相符,利用ABAQUS软件可以模拟土石坝在实际工程中的受力情况,对于今后土石坝内部应力研究有一定的意义。

The inter stress and strain changes of earth-rock dam under earthquake loading get more and more attention. Taking the earth-rock dam of Xiaogujia reservoir in Qingyuan county, Fushun City, Liaoning Province as the example, the stress and strain changes under earthquake loading are simulated by using the ABAQUS software. Based on the calculation results, the x direction displacement, the permanent deformation distribution and the acceleration variation curve of the earth-rock dam under earthquake loading are obtained,which is consistent with the theory. The ABAQUS software could be used to simulate the force condition of the earth-rock dam in the actual projects, which has certain significances for the internal stress study of the earth-rock dam in the future.
