【摘要】 对原有的响嘡三维场地条件影响台阵进行了扩建改造。增设了一个深度为47m的测井,对钻孔土样进行了土动力学测试,弥补了缺乏详细土层特性资料的缺陷。新老测井观测点均架设了电话线路,实现了观测中心与台阵之间的远程监控和数据传输。已经获取的一批中小地震近场记录可以用来进行盲测研究。更多还原

【Abstract】 A new observation station which consists of a downhole accelerometer and a surface accelerograph,was deployed in the Xiangtang three dimensional array for studying the site effects on seismic ground motion in 2000.The dynamic features tests of the borehole soils samplings were fulfilled to make up the defect of soil data.The remote communication was established between Beijing Strong Motion Observation Center and the Array.A number of accelerograms obtained in small and moderate earthquakes can be used for the "blind prediction" studies.更多还原
