摘要：Accurately grasping the spatial distribution characteristics of fractures is an important basis for computation and analysis of rock engineering. On the basis of field investigation, probability statistics, and numerical simulation, the fast modeling method of fracture with special probability and statistical distribution is proposed. The server connection between COMSOL and MATLAB is established. In the COMSOL with MATLAB programming environment, the fast modeling program of fissure space structure is developed. Aiming at the difficulty of mesh generation due to high fracture aspect ratio, programming language was used to interpolate the material parameters of fissure space structure and construct the equivalent assignment method of fissure space structure. Based on the field fracture investigation in an underground mine, probabilistic data analysis of fracture data is carried out, and the fast modeling and equivalent assignment method is applied to realize the efficient modeling and assignment for the field investigation of fissure spatial structure.
