Abstract

During the construction of tunnel，the excavation process would lead to the groundwater seepage field redistribution and groundwater level drawdown. However，the effect of excavation-induced groundwater level drawdown on tunnel inflow had not been considered in common analytical method. Through the numerical calculation，the change of seepage field after tunnel excavation is analyzed. And based on the numerical solution，the analytical method for calculating the tunnel inflow and lowered water level is proposed by considering the effect of groundwater level drawdown. The results indicate that the pore water pressure around the tunnel and the water level gradually decrease over time during the excavation process. The pore water pressure changes dramatically in the scope of 5 times tunnel diameters and the water table reduces by 26.3% to 56.7%. After the seepage field stabilization，the lowered water level is closely related to the tunnel radius and initial water level，not to the permeability of surrounding rock. Compared with traditional analytical solution and numerical solution，the analytical method proposed can conveniently solve the lowered water level and tunnel inflow for the cases with horizontal and inclined groundwater level.

Key words： tunnel engineering seepage water inflow numerical analysis analytical method
