The two-dimensional high density electrical method can overcome the limitation of three-dimensional high density electrical method on topography and cost. The 3d high density electrical method can effectively solve the deficiency of two-dimensional high density electrical method in detecting space morphology. Therefore, Three-dimensional inversion of data obtained from two-dimensional exploration of high density electrical method has not only realized the three-dimensional visualization of underground space structure but also avoided the impact of topography and cost. Applying this method to the exploration of karst caves, using DUK-2A high density electrical system to collect data, and then convert the two-dimensional high density data into three dimensional inverse data, the results of the inversion can be obtained by any 3d dielectric section, by Slicer Dicer, in order to get rich information about the cave, finally, the interpretation of karst cave is made by combining the 3d dielectric section and borehole data, providing scientific basis for the smooth operation of the project, the feasibility and validity of this method are proved.
