甘孜地震台地电阻率观测数据干扰分析

Analysis of Interference Factors of Apparent Resistivity at Ganzi Seismic Station

通过对甘孜地震台地电阻率观测数据的分析,发现观测数据会受观测环境、漏电、雷电和降雨等因素的影响而发生变化。对地电阻率观测到的各类干扰数据变化特征进行总结,有助于排除前兆信息中的干扰因素,提高地电阻率观测资料的使用价值,夯实用地电阻率观测资料预测地震的基础。

Through the analysis of the observation data of apparent resistivity at Ganzi seismic station,we suggest that the observation data can be affected by the observation environment,electric leakage,lightning,rainfall and other interference factors.It is helpful to eliminate the interference factors in the precursory information,to improve the value of the apparent resistivity observation data,and consolidate the basis of practical apparent resistivity ob-servational data for earthquake prediction.
