摘要
本文介绍了近几年获取的强震记录中显示出的地震动特征 ,诸如近断裂的破裂方向性效应、上盘效应、影响地震波传播的地壳波导效应、沉积盆地的放大效应和盆地边缘效应 ;归纳了强地震动估计的三种方法 ,简要综述了经验性衰减模型、预测强地震动的随机法和宽频带格林函数法 ;
It is briefly described about the strong ground motion characteristics emerged from the strong motion accelerograms recorded from recent devastating earthquakes. They are the effects such as rupture directivity, hanging wall, crust wave guide, along with the amplification effect and the edge effect of sedimentary basin on strong ground motion. Three methods, i.e. experimental attenuation model, random vibration method and broad band Green function method for strong ground motion prediction were also summarized and reviewed in this paper. Finally, the key points in predicting the strong ground motion caused by active faults are discussed.
