Based on three-dimensional geological modeling of geological section

With the development of computer technology and geological modeling study of the gradual maturity, 3D for the engineering geological modeling and information visualization analysis system of opportunities and challenges brought about. Have carried on the detailed introduction to the three dimensional geological modeling tool and the method. Summarized the three dimensional geological modeling basic step. Surface topography information deduce the initial construction of the geological model project. Carry out the calculation of occurrence. How to use the discrete value of the occurrence of information, production level surface equation method , And study of the surface intersection, Initial generation of 3D geological model .This paper discusses the adoption of the new access to the geological information on how to modify the initial model editor .Application algorithm for the generation of surface fitting interpolation. Display system for the section of geological strata, faultage and three-dimensional geological model of the effect drawings of block geological. At the same time, it provides a reliable scientific authority for the decision-making of the underground construction projects.
