ANALYSIS OF RESOLUTION INFLUENCE FACTORS OF HIGH-DENSITY ELECTRICAL METHOD AND ITS APPLICATION
摘要
Abstract
In recent years,high-density electrical method have been used more and more widely and the researches on resolution influence factors analysis of the high-density electrical method have been drawn much attentions.This paper takes the partially erect anomaly of a uniform half-space as detect target,building different models to simulate and analyze with the Wenner high-density electrical device,employing 2DRES software to process forward and inverse numerical simulation and analysis to obtain the effects of the terrain,resistivity differences,depth to diameter ratio and deepening on the high-density electrical probe resolution.The results show that the undulating terrain makes the apparent resistivity anomaly location displaced,shape distorted and the resolution reduced;the detecting resolution of high-density resistivity method increases with the increase of resistivity difference;the detecting resolution decreases with the increase of depth to diameter ratio,and the detecting resolution increases with the increase of extended depth when the lateral width of certain anomalies reaching a critical level.Finally,the recommendations to improve the detecting resolution are given by combining the theoretical analysis and the engineering application.关键词
