This Paper present design parameters of grouting by reviewing several published equations and the results of coupled analysis considering the difference of permeability between soil and grouted zone. Also, the feasibility of couped analysis in the design of grouting is studied for seeping water quantity into tunnel, displacement of tunnel face, drawing down of groud water table, settlement of ground and stress of tunnel supports.
