The three dimensional high density resistivity method has been popularized and widely applied inengineering.It is very important to improve the resolution of the data processing and interpreting.This paper isbased on the theory of threedimensional high density resistivity method and proposed to set up the differentgeoelectric models.It utilizes the finite difference method and the leastsquares method to process the data.Andthen,the paper uses the results of the interpretation to analyze spatial orientation and morphological effect in orderto obtain the change rules of the abnormal body.Simulation and analysis results show that the threedimensionalhigh density resistivity method has a good accuracy in detecting the position of abnormal body.
