Abstract

Tunnelling below the groundwater table influences the hydraulic regime in the surrounding ground. This will, in turn, cause seepage into the tunnel through the pores and discontinuities and often produces a long-term interaction between the tunnel and the ground. In this paper an attempt is made to identify the behavior of surrounding ground due to seepage, and ground reaction curves (GRC) considering seepage forces are presented for a tunnel under drainage conditions using an analytical method. It is found that the flow of groundwater has a significant effect on the radial displacement of a tunnel wall. While the effective overburden pressure is reduced by the arching effect during tunnel excavation, seepage forces still remain. Therefore, the presence of groundwater induces large radial displacement of the tunnel wall compared to dry conditions.
