摘要
本文用二维有限元方法,研究了地表地形及埋藏地形对地震动反应的影响;同时对较为平坦的区域,进行了一维地基地震反应分析。本文采用的二维计算方法及对一维结果的校正方法在国内地震小区划工作中首次使用,为今后的研究提供了一条新的途径。
Making use of two—dimensional finit element method, influence of surface and buried topography on the response of ground movement has been studied in this paper. Meanwhile, the analysis of seismic response of one—dimensional foundtion has been also given. It is first to apply 2—diemensional computation and 1—dimensional result correction to seismic microzonning.
