摘要

本文利用美国加州强震观测计划（CSMIP）3个台阵的在23次地震中取得的303条地震记录，系统地研究了地震动相干性在不同深度、不同场地条件、不同地震震中距情况下水平分量和竖向分量的变化规律，并提出了合理的经验相干函数模型。结果表明，综合考虑上述各种影响的相干函数模型能使得分析结果更加完善可靠。

Abstract

The strong ground motion coherence variation with depth, both in horizontal and vertical directions, is studied by utilizing 303 recordings in three arrays of CSMIP, USA. New coherence model is suggested in this paper, which indicates that the epicenter distance and site condition may affect the coherence variation with depth.
