“九五”四川数字强震台网的建设与发展

Introduction to the digital strong motion accelerograph network of Sichuan

在2005年以前的4年时间里,四川省相继建立了若干数字强震子台,以前的8个布局不合理的老旧模拟式强震台全部退役,取而代之的是22个分布于四川省内各主要地震多发地带的数字强震台,从而结束了连续十几年无数字强震观测成果的历史。现在获取记录的数量和质量正在逐年成倍增长,与仪器相关的软件分析系统得到进一步改进,在数据常规处理后,还将四川省现今所有的数字强震仪都转变成了“烈度仪”,为防震减灾工作提供了最直接服务的观测资料。

During 4 years last, the digital strong motion accelerograph network of Sichuan has been set up. New network consisted of 22 digital strong motion accelerograph stations that are located along the main seismic belts in Sichuan province. The observation data are accumulated also and some of recording data are presented with figures.
