    Abstract: It is of crucial importance to develop an efficient numerical method to investigate the mechanism of grout diffusion and migration in fractured rock masses. However, most existing models only concentrate on the grout flow in a single fracture and most existing algorithms for large-scale fracture networks have high computational cost. A new dynamic diffusion and migration algorithm for grout was proposed and applied to the two-dimensional fracture network in this paper. Based on the geometric relationship between the fracture network nodes, an effective and feasible generation method of the connectivity matrix was proposed to realize the digitization of the topological structure of the fracture network. Finally, the Fracture Networks Grouting Diffusion Program (FNGDP) was developed to visualize the entire process of grout diffusion and migration in fracture networks. Compared with other algorithms, the proposed algorithm can realistically simulate the grouting process and greatly reduce computing time.
