摘要

基于运动学震源模型,以弹性半空间作为传播介质模型,本文采用显式有限元数值模拟方法进行强地面震动数值模拟,根据模拟结果考察了震源深度、断层破裂子源大小、破裂速度和断层走向等震源参数对地震动相干函数的影响,结果表明:震源深度和断层走向对相干函数的影响较大。并根据统计结果给出了一个基岩地震动的相干函数模型。

Abstract

Using an elastic half-space model, the effects of source parameters on spatial variation of stochastic ground motions are studied in this paper by the explicit finite element method and kinematic source model. The results show that the fault depth, the rupture velocity, the size of sub-source and the fault direction have influence on coherency function, especially for the fault depth and the fault direction. At last, a coherency model for base-rock site by statistic method is proposed.
