广东省“十五”项目测震台站台址勘选结果分析

Analysis of seismic stations exploration results for the tenth-five year plan in Guangdong Province

利用地震台址勘选过程中产出的地脉动背景噪声数字记录,计算勘选出的各台站背景噪声地脉动速度均方根值(RMS)、噪声功率谱密度等数据。成果在于得出各地震台站的背景噪声水平和等级分类,为将来计算各地震台站的场地响应及震级修正值等测震学研究提供基础资料,是对“广东省数字地震观测网络”项目测震台站勘选工作的总结与评价。

By calculating the root-mean-square （RMS） and power spectrum density of seismic station＇s background noise by use of the earth motion noise data with recorded in seismic station exploration, we have obtained the background noise levels and grades of all stations. It provides basic data for calculating site respond and seismic magnitude correction value of seismic stations. This is summary and estimation of the work for seismic stations exploration of the tenth-five year plan in Guangdong Province.
