Abstract This study is to investigate the diffusion mechanism of an ideal self-expansible grout with known density variation over time in rock fracture. Based on the viscous fluid mechanics，a radial diffusion model of the expansible grout in a single water-free fracture is deduced considering the factors such as the initial grout filling range，fracture aperture，time and expansion coefficient. The corresponding axisymmetric model in typical grouting conditions is established with the general CFD software Fluent to verify the analytical model numerically. The numerical results of the grout diffusion radius，pressure and flow velocity distribution are in good agreement with the analytic results at different times under different conditions，which proves the rationality and correctness of the diffusion model.

Key words： fluid mechanics self-expansible grout diffusion model crack grouting numerical verification
