C-S slurry and GT–1 slurry aretwo types of quick setting slurry which are frequently-used in dynamic grouting engineering. Considering time-dependent behaviour of viscosity，and using COMSOL Multiphysics as the finite element software，numerical model of crack grouting process in running water was established. The law of slurry diffusion and its influencing factors were studied. Comparing numerical simulation and test results，rationality of numerical simulation is verified. Results show that：Running water restricts the range of slurry diffusion，and significant differences exist between along the flow direction and against the flow direction. Pressure around inflow boundary is gradually approaching the distal groundwater pressure. In initial stages of grouting，velocity in regions near the no flow boundary and outflow boundary is higher than other regions. In later stages of grouting，velocity in different position changes gently. Under the present experimental conditions，initial hydrodynamic flow rate and grouting rate are positive correlated with velocity and pressure in crack. Furthermore，grouting rate shows more effect on pressure in crack than initial hydrodynamic flow rate. Slurry diffusion law of C-S slurry and GT–1 slurry are similar，however，difference of time-dependent behavior of viscosity leads to quantitative differences of diffusion.
