    • Abstract
  • Aiming at the problem that it is difficult to establish a model for complex geologic body for discrete numerical methods, based on the platform of Microsoft foundation Classes (MFC) in VC++, a procedure is developed to establish a three-dimensional spherical particle numerical model. By usingthe open graphic library OpenGL, the modeling is visualized in the procedure. Based on the surface-excavating algorithm and the tunnel-excavating algorithm, complex ground surface and various tunnel spaces can be obtained from the model. A modeling example indicates that it is able to establish a spherical particle model for large-scale complex geological body, suitable for the modeling of various kinds of common engineering geological bodies, and conducive to more application of discrete numerical methods like DEM and DDA in large-scale engineering.
