Abstract: Using ANSYS software as basic platform, and based on the condition of level, slope and triangle terrain, this paper numerically analyzed the influences on observation data caused by 2 meters thickness low-resistivity layer formed by raining. Moreover, according to the condition of different distance, this research analyzes the influence of ebb and flow of river water on observation data obtained from the geoelectric observation station at the side of a river. Those factors are seldom taken into account in the past practical observation. The results gained by this paper have reference to the correction of practical geoelectric observation data and judgment on earthquake anomaly.
