嘉山地震台模拟和数字记录地震对比分析及台基评价

Comparative analysis of the analog and digital records and station basement appraisement in Jiashan Seismic Station

通过对嘉山地震台测震模拟与数字观测系统并行运行观测资料的对比分析,阐述了测震台宽频带数字地震观测系统,在区域地震台网速报和观测资料应用研究方面的作用和价值。同时,也对嘉山地震台的台基地动噪声水平进行了基本评估,提出了改善嘉山地震台地震检测能力应采取的措施。

In this paper, the affect and value of the digital broad band seismic observation system for the regional seismic network quick report and observation data application are described based on the comparative analysis of analog and digital seismic observation system and the observations in Jiashan Seismic Station. Meanwhile, the noise level of the station basement is also appraised. The measure for improving the earthquake monitoring capability of Jiashan Seismic Station is also presented here.
