【摘要】 本文对地震动地形效应的影响因素及其规律进行了阐述和分析。主要对局部地形几何形状,入射波的入射角度、频率,震源相对位置及震源深度等因素对地形效应影响的国内外研究现状进行了综述。同时,介绍了地震数值模拟在地震动地形效应研究中的应用,并对进一步研究提出了一些建议。更多还原

【Abstract】 A brief review of experimental and theoretical results about the effect of topography on ground motions,which include local terrain geometry,incident angle and frequency of incident wave and focal location and depth,is given in this paper.Meanwhile,we introduce the situation and application of the seismic numerical simulation of topographic effect on ground motion,and some suggestions are proposed for the further study.更多还原
