Abstract: In order to be more abundant geological target of electrical characteristics as well as more intuitive geological structure,in the case of conditions to carry out three-dimensional high-density electrical resistivity tomography to work with the two-dimensional observation method of different,three-dimensional approach to the work area venues require a higher,environmental conditions and other factors on the three-dimensional system,a greater impact. In this paper,obtained under the condition of some of the complex three-dimensional results of an analysis that in practice,in accordance with these complex conditions,targeted to take the necessary measures and methods,you can get more good results to solve the engineering geology and other issues.
