地下结构地震动力响应中地震波的分析研究

Research of Seismic Waves in Analysis for Seismic Response of Underground Structure

地下结构地震动力响应分析首先需要对地震波进行合理的分析,其主要包括地震波的选择、波的频谱分析、滤波和基线校正4个方面,这是正确进行地下结构地震动力分析的非常关键的环节.以课题研究中地震局提供的地震波为例,从多个方面分别对地震波进行分析和研究,从而获得满足地下结构地震动力分析要求的地震波.

Seismic response analysis of underground structure first needs proper analysis for seismic waves,which mainly include seismic wave selection,wave spectrum analysis,filtering and baseline correction.This is the key factor to underground structure seismic analysis.Based on the case of seismic waves provided by the earthquake bureau,we analyze the seismic wave from several aspects respectively,and then we can get the seismic waves meeting the requirements for study of seismic analysis to underground structure.
