Comparison between model test of grout diffusion distance of fracture with different dip angles in literature41 and theoretical calculation results in this paper :(a) grout diffusion distance of fracture with dip Angle of 0°, (b) grout diffusion distance of grout with dip Angle of 10° (grouting pressure of 0.01 MPa), and (c) grout diffusion distance of grout with dip Angle of 10° (grouting pressure of 0.1 MPa).
