新丰江水库区和平地电站电阻率深孔多电极抗干扰观测实验

摘要
随着社会经济的快速发展,传统的地震地电阻率观测想避免环境干扰的影响已经是不可能的事情。在这种形势下,由横向向纵深发展的深埋电极电阻率观测方法正得到越来越多的重视和研究。通过利用和平地电站已开展近20年的深孔电阻率观测试验的有利条件,进行深孔多电极组合实验观测研究。总结了多种实验结果,证明在深孔中设置多电极组合的优势,并表明电极只要埋人地下一定深度后,就能达到压抑地表的干扰影响。
With the rapid development of society and economy,it's impossible to avoid interference of environment for traditional earth resistivity observation.In such a case,more and more attention and research has been paid and done to the method of observing buried electrode resistivity which develop from horizontally to vertically.This article makes use of the advantage that deep-hole resistivity observation experiment has been carried out nearly 20 years in Heping seismic station,for researching the deep-hole multiple electrode combination experiment,and summarizes many experimental results,which show the advantages of setting multi-electrode combination in deep-hole,and also indicate that the surface interference can be inhibited as long as electrode is buried with a certain depth.
