河北大柏舍台深井与浅层地电阻率观测对比分析

Contrastive Analysis of Georesistivity in Deep-well and on Ground at Dabaishe Station

摘要: 介绍了河北大柏舍台深井与浅层地电阻率的观测概况，对其观测精度、抗干扰能力、年变规律等进行了对比分析。发现深井地电阻率在观测精度、抗干扰等方面均优于浅层地电阻率；深井地电阻率年变规律与浅层地电阻率有着较大差别，浅层地电阻率2个测道的年变化明显，而深井地电阻率的年变不明显。

Abstract: This article introduces the georesistivity observation in deep-well and that on ground at Dabaishe Station in Heibei province, analyzes the accuracy, anti-interference ability and the law of annual variation etc. The analysis shows that the observation accuracy and anti-interference ability observed in the deep-well are better than that of the ground observation, and furthermore the annual vibration of the georesisitivity observed on ground is remarkable, while that of the georesistivity observed at the deep-well is not.
