Then, the interface program that transforms the mine design model to calculate the model was compiled using FORTRAN, and the specific steps of the program implementation were described using a large iron and copper mine modeling example.įirst, the relationship between the FLAC3D and the SURPAC unit data was examined, and the transformation technique between the data was given. The results show that the proposed transformation technique and its corresponding interface program transformed the SURPAC model into the FLAC3D model, which expedited FLAC3D modeling, verified the validity and feasibility of the transformation technique, and expanded the application spaces of FLAC3D and SURPAC. IntroductionĪlong with the rapid development of computer technology in recent years, the numerical method along with artificial intelligence technique has become an important mean of analyzing and calculating modern engineering technologies and forecasting engineering stability and reliability. FLAC3D (numerical calculation software) has been extensively recognized and applied for analyzing geotechnical issues. FLAC3D could be used to examine the changing rules of the field effect of rock mass from the macrotrend and it is suitable for most engineering mechanics issues, particularly for analyzing material elastoplasticity, large deformation, rheology prediction, and for geotechnical numerical simulation of construction processes.
However, FLAC3D is quite difficult to use for pretreatment modeling, particularly in the geological body of complicated multimedia and multiboundaries. Thus, engineers often use models by simplifications to approximately describe geotechnical models to solve this problem above. Surpac drillholes to string file how to#īut different lithologies have different mechanical features excessive simplification of the model would reduce the reliability of the numerical simulation results.
