合肥台地电阻率干扰综述

A Summary of the Earth Resistivity Disturbance at Hefei Station

本文首先叙述了合肥台地电阻率值ρs的观测环境,并根据合肥台近年几次ρs的异常变化,通过初步理论分析,找出了DD-1接地体、电缆沟开挖、大气降水、太阳黑子引起的自然电场对ρs的干扰,为以后排除和识别地电干扰起参考作用。

This article first describes the monitoring environment of Hefei Seismic Station with the earth resistivity value ρ8, and then makes a preliminary theoretical analysis according to the abnormal changes of recent years and attempts to find the reasons for disturbance so that it can be of some reference to identifying and eliminating disturbance factors in the monitoring of earth current in furore.
