摘要
浚县地电阻率观测数据自2017年5月开始,到2019年9月,每次强降雨或者长时间降雨过后,EW向电阻率均出现大幅下降阶变异常。针对异常进行排查,依据三维影响系数在地表的分布,排除或锁定干扰源,为下一步的实验提供参考和数据支持。
from May 2017 to September 2019, the observation data of earth resistivity in Junxian county showed a significant step-by-step decrease in EW direction resistivity after each heavy rainfall or long-term rainfall. In order to provide reference and data support for the next step of the experiment, we should check the anomalies and eliminate or lock the interference source according to the distribution of three-dimensional influence coefficient on the surface.
