摘要

在美国加州特基平地进行的国际地震场地效应盲测试验中，用传递矩阵法及由此所发展的计算软件较成功地预测了特基平地试验点的地震动响应。盲测结果表明，表面地质模型参数对于正确的预测地表的地震动响应是十分重要的。比较预测资料和计算结果揭示，除了界面深度外，地震波的入射角、Ｓ波速度以及Ｑ值等参数对于地震动的预测是十分重要的。
Blind test for site effect of surface geology the authors took part in,is discussed in this paPer.This international exPeriment was held in Turkey flat,California,USA.We well predicted the seismic vibration at the experimental site of Turkey flat by the propagation-matrix method and the corresponding computer software was developed by us,The results of the blind test show that parameters of geology model are very important for the prediction of the response of surface seismic shake.Comparing the observed data and results of computation reveals that incident angle of seismic waves,velocity of S wave,Q value of strata media as well as depths of interfaces all have the noticable influence on the prediction of seismic vibration.
