地震动参数与地震灾害相关性分析以汶川震区地震滑坡灾害为例
Analysis of correlation between ground motion parameters and earthquake disasters:A case study on earthquake-induced landslide hazard in Wenchuan earthquake area
摘要
Abstract
A method was designed by taking the case of landslide hazards induced by the Wenchuan earthquake to study the correlation between parame-ters reflecting different ground motion characteristics and earthquake-induced landslide hazards.The results indicate that Arias intensity is the best parameter for disaster evaluation,which is more suitable for small region estimation.And the peak ground acceleration also behaves well in correlation analysis,but it is more suitable for evaluation of large area.The parameters,related with dura-tion and frequency,can provide accessory information in analysis on mechanism of earthquake damage in concrete site.The vertical component plays an impor-tant role in evaluating earthquake-induced landslide hazards.The results have certain reference significance for selecting evaluation factors in studies related with earthquake-induced secondary hazards.关键词
