【摘要】 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。更多还原

【Abstract】 It is found that deep buried electrode observation can effectively reduce the influence coefficient of surface,relative to surface electrode observation after some analysis on the comparison 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 addition,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.更多还原
