| Abstract: | The three dimensional high density resistivity method has been popularized and widely applied in engineering. It is very important to improve the resolution of the data processing and interpreting. This paper is based on the theory of three-dimensional high density resistivity method and proposed to set up the different geoelectric models. It utilizes the finite difference method and the least-squares method to process the data. And then, the paper uses the results of the interpretation to analyze spatial orientation and morphological effect in order to obtain the change rules of the abnormal body. Simulation and analysis results show that the three-dimensional high density resistivity method has a good accuracy in detecting the position of abnormal body. |
