3D dynamical response analysis of slope in open- pit using ANSYS

运用ANSYS软件初步分析三维边坡的地震动力响应问题，结合某露天矿山工程实例，建立了边坡三维计算模型，输入地震波，对该边坡进行了有限元模态分析和应力、位移、速度和加速度响应的时程分析。模拟结果再现了地震波作用全过程及边坡体内部关键位置相关量的变化过程。

In this paper, 3D dynamical response analysis of slope in open-pit was researched using ANSYS. The geology model of a real opencast mine slope was analyzed thoroughly, the 3 - D model was established using ANSYS program. The earthquake wave was input. The dynamic response analysis of slope is applied, and the stress, displacement, velocity and acceleration were researched. The transformation of slope＇s parameters under earthquake was reappeared .
