SURFER SOFTWARE PLATFORM BASED COMPLEX THREE - D IMEN2 SIONAL GEOLOGICAL D IGITAL MODELS FOR PRE - PROCESSING OF FLAC3D

Digitalmodeling of comp lex three - dimensional geological body is always a difficulty in p re - p rocessing of FLAC3D. Therefore, a new modelingmethod is put forward in this paper. The three - dimensional geological information of ground surface and strata interfaces are extracted and transformed in the Surfer software. Using Surfer as a transitional p latform, the information can be exported from Surfer and then is retransformed by p rogram made by Fish language embedded in FLAC3D. According to above p rocess, the model data for FLAC3D is generated and comp lex three - dimensional geologicalmodel can be created quickly and accurately in p re - p rocessing of FLAC3D. The feasibility and simulating effect of the method is verified by combining p ractical p roject. The result shows that the modeling method is simp le, p ractical and with bettermaneuverability. Thereby the method is a new, good approach in pre - processing of FLAC3D.
