摘要

地震是地球内部缓慢积累的应力突然释放引起的地球表层的振动。地震产生原因多种多样,一次地震是各种因素综合作用的结果。对抗震工程而言,地震动的特性主要可以通过其四要素来描述,即地震动的振幅、频谱、持时和空间相关性。本文系统分析了汶川地震产生的原因,并进行其地震动特性分析,从振幅、频谱、持时和空间相关性等4个方面分析汶川地震。
An earthquake is a phenomenon that results from and is powered by the sudden release of stored energy in the crust that radiates seismic waves.The cause of earthquake is various,and an earthquake always caused by the total use of them.According to earthquake engineering,the properties of ground motion can be described as four factors,which is amplitude,spectrum,duration time and space relation.In this paper,the cause of Wenchuan earthquake is analised systematically,and the properties of ground motion is analised by four aspects,including amplitude,spectrum,duration time and spatial correlation.
