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。
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 georesisi- tivity observed on ground is remarkable, while that of the georesistivity observed at the deep-well is not.
