Abstract:The non-similarity structure of fault restricts the development of 3D visual modeling in geological applications. Listric fault is a typical fault along which the strata in upper and lower walls are not corresponding from one profile to another. This is the non-similarity structure of fault. Based on the non-similarity structure of listric faults,a configuration similarity method(CSM) is brought forward for 3D modeling of the non-similarity structure. CSM is to transform or split the geometric configuration of listric faults and to make them corresponding one by one between two profiles. The software used in this paper is Geo-View,which is 3D visual geological information system,developed in China University of Geosciences(CUG). Based on two profiles,the 3D digital body of listric faults has been built,and the vector cut included the incline,strike,level and oblique orientations has been finished. CSM for 3D modeling may used for reference for others in fault modeling,and be applicable for geotechnical engineering,basin modeling and mining geology. CSM has been applied to three oil and gas fields,one coal mine and one sliding mass,in which the fault modeling has been solved effectively.
