Abstract
Because of the different types and function of the Underground engineering, a large number of geological drilling in construction area cost high, and will cause unnecessary security hidden danger in later construction. In consideration of the accuracy of other existing geological survey equipment is so poor that can not meet the data requirements of geological modeling, In this paper, we select a combination method between high density resistivity survey data and drilling data of Geological information access and data fitting, through the error analysis of the results, Two classes of data fitting equation are obtained, and through this method, the accuracy of the data of geological modeling are effectively corrected.
