* The paper uses the BIM design platform Revit as the main program for modeling and debugging, relying on Lizheng survey drilling data, based on the Revit API secondary development technology and its modeling method, to carry out various algorithms involved in 3D geological modeling .The program design realizes automation and rapid establishment of 3D geological entity model, and enables it to have more comprehensive geological information query, section analysis and other functions. At the same time, in order to solve the problems of insufficient original borehole data or uneven borehole distribution, the paper proposes a virtual borehole generation method based on the moving quadric surface fitting interpolation algorithm, which effectively improves the modeling accuracy and the visualization effect of the model.
