Development of Station Site Response Software Based on Spectral Ratio Method

基于场地响应谱比法的计算方法,在Matlab平台下开发场地响应求解计算软件,该软件直接批量读取台站地震sac数据记录、仪器参数文件,对应地震震相文件,对测震台网台站实现批处理大量地震记录,并产出基于谱比法的场地响应值。软件利用相关控件优化使用者的数据处理过程,操作简单方便,可以用于新建固定台站场地响应计算、也可用于地震应急时期,流动台站场地响应计算,具有一定的应用价值。

Based on the calculation method of the site response spectrum ratio method,this paper develops the calculation software of site response under the Matlab platform.The software can directly reads the seismic sac data records,instrument parameter files of the station,and the corresponding seismic phase files in batches,realizes batch processing of a large number of seismic records for the seismic network stations,and outputs the site response value based on the spectral ratio method.The software uses relevant controls to optimize the user's data processing process,which is simple and convenient to operate.It can be used for site response calculation of new fixed stations,as well as for site response calculation of mobile station in earthquake emergency period,and has certain application value.
