海安地震台深埋电极地电阻率观测分析

摘要

It is found that deep buried electrode observation can effectively reduce the influence coef-ficient of surface,relative to surface electrode observation after some analysis on the compar-ison observations of deep buried electrodes and surface electrode at Hai′an Seismic Station. And it has obvious significance on improving the annual variation characteristics.In addi-tion,the deep buried electrode has obvious significance to avoid interference on the surface and improve the accuracy of observation.Deep buried electrode observation mode provides a new idea for the ground resistivity measurements for elimimating the interference come from metal,rainfall etc.%通过对海安地震台深埋电极和表层电极对比观测结果进行分析，发现相对表层电极观测，深埋电极观测能有效降低表层影响系数，对改善年变特征具有很好的效果，并且在避免表层干扰和提高观测精度上具有明显意义。深埋电极观测方式为解决地电阻率场地中的金属干扰、降雨影响等提供新的思路。
