Basing on the theory of maag cylindrical diffusion, back grout diffusion radius and grouting pressure formula of shield tunnel were derived in two cases of the viscosity time-dependent behavior or not.The distribution law of diffusion radius and the pressure to segments were obtained by applicating the spreading model in some project.The results show that grout diffusion radius and grouting pressure both increase with the increasing of grouting time and grouting pressure whether considering the viscosity time-dependent behavior or not.In the same grouting time (pressure),the calculated values that unconsidering the viscosity time-dependent behavior are bigger than the values of considering.
