依靠ANSYS软件的辅佐运用FLAC岩土软件,对不同高度边坡进行了地震响应分析,抓住动力反应三量中的位移和加速度做重点研究,通过对位移和加速度模拟得到的时程曲线分析,得出地震波从底部传到坡顶需要一定的时间,提出目前动力反应三量放大系数等值线的不妥之处,探讨了建立同时刻的动力反应三量放大效应时程等值线的意义。

Through applying FLAC geotechnical software with the auxiliary of ANSYS software, the paper carries out earthquake response analy- sis for the slope with various heights, and mainly studies the displacement and acceleration included in dynamic response. It obtains the time- history curve analysis by simulating the displacement and acceleration. And then, it concludes that there is certain time for seismic wave trans- mitting from the bottom to the top, and points out defects of three quantity amplification coefficient in current dynamic response, and finally ex- plores the meaning for three quantity amplification coefficient of dynamic response.
