摘要

介绍了广西“十五”新建数字化地震台台址的地噪声数据,这些数字测震资料代表广西不同台基的地噪声参数。利用童汪练研究员传授的地噪声分析软件和MATLAB工具软件,实现数字地噪声功率密度谱、频谱、地脉动周期(频率)特性初步分析。讨论了广西不同地质环境、岩性对台基噪声的影响。
In This article, it is introduced of the ground noise data on the site of digital seismic stations, new built in Guangxi area during the State′s Tenth Five year plan. These digital seismic data represent the ground noise parameters of different geology characteristic of the station base. With the ground noise analysis software provided by Professor Tong Wanglian and Matlab tool software, the characteristics of ground noise, such as power spectral density, frequency spectrum and the period of ground flutter, are analyzed primarily. The effect of geological site and lithologic characters of station base on the site noise in Guangxi area are also discussed.
