山东省数字强震台站建设及其汶川8.0级地震的纪录特征

THE CONSTRUCTION OF THE DIGITAL STRONG MOTION OBSERVATION STATIONS OF SHANDONG PROVINCE AND ITS RECORD CHARACTERS OF THE WENCHUAN EARTHQUAKE

摘要: 介绍了山东省强震观测台站在十五期间的建设情况,通过汶川8.0级地震的检验,表明山东强震观测台站的观测仪器运行良好,强震台站的场地条件与强震动参数存在明显的相关关系,强震动的土层放大效应非常明显,其影响对结构第一周期在1s-8s左右的建筑物具有重要的作用。

Abstract: We give a summary to the construction of the digital strong motion observation stations of Shandong Province.The equipments of the observation stations run well during the Wenchuan earthquake, the parameter of earthquake strong-motion date has obvious correlativity with the field condition of the stations.The amplificatory effect of soil sediments to the earthquake strong motion is very distinct.This character has great function to the building and construction whose basic period are 1s~8s.
