河北省数字地震台网子台地动噪声分析

Analysis on the ground motion noise of substations in Hebei Digital Seismic Network

通过对河北省数字遥测地震台网子台地动噪声分析,各个子台的台址环境和观测仪器的性能基本优良,能够适应宽频带地震观测要求。由于子台受当地经济发展、城市规模扩大以及交通建设等影响,部分台址观测条件受到影响。可以有针对性地对部分台站进行环境改造,为地震监测预报创造更好条件。

Through analysis to the ground motion noise of the substations in Hebei digital seismic network, it shows that the environment of each substation site and performance of instruments are basically good, and can meet the requirement of broadband seismic observation, parts of station sites has been affected by constructions, but it can be improved with environmental reconstruction.
