摘要
本文通过弹性半空间内位错源的数值解法研究了基岩地震动相干函数,采用有限元方法分析了一些典型场地的地表地震动相干函数,两者的对比结果表明:复杂场地对地震动相干函数的影响强烈。
By the numerical method for dislocation source of fault in homogeneous elastic half-space, coherency function of ground motion for base-rock site is studied in this paper. And coherency function of typical sites is analyzed by FEM. Results show that complex site strongly affects spatial variation of ground motion.
