Numerical simulation of grouting in rock mass

It is considered that grouts only flow in fracture network with good connectivity and penetrability. Based on the simulation of fracture network of rock mass, the seepage model of the Binghamian grouts flowing in fracture network was developed. On the basis of the model, grouting was simulated. In addition, the deformation of fractures and its effects upon grouting were studied during the process of grouting. The results indicate that the grouting effect can be predicted and improred by the model.
