Abstract:

The construction of the 3D visualization model and the numerical model of complex geological body is critical in mine, geotechnical, hydraulic and hydropower projects. Aiming at the disadvantages of modeling complex geological body of mine by numerical simulation software, such as the modeling process complex and difficult and mesh generation has great workload, Combined with the advantages of modeling complex geologic body of mine use mine software, on the base of studying the differences between wireframe model and block model, a kind of new method of numerical modeling and geologic body visualization based on complex mine is proposed based on wireframe model. According to the different characteristics of wireframe, taking surface and cavity model as examples, an effective method of converting Surpac surface model and solid model into MIDAS/GTS numerical model exactly is researched; this method has been used to research the cavity stability analysis of Dongguashan Copper Mine successfully. The results show that the new modeling method is feasible and effective, so as to offer a new modeling method for mine design, safety analysis and complex geological body rock soil engineering numerical simulation, etc.

Key words: geological body visualization, 3D geological model, numerical model, Surpac, MIDAS/GTS
