TLDR
In this paper, the effect of different drainage conditions on porewater pressure distributions, flow nets, and lining stresses in drained tunnels is investigated, and the case study of the planned South Blue Line Extension subway tunnel under the steady-state groundwater flow condition is performed for four different drainage condition (sealed, fully-drained with zero water pressure or a constant total head, and invert only-draining) along the tunnel circumference.About:

Investigation of steady water inflow into a subsea grouted tunnel
TL;DR: In this paper, the pore pressure distribution in the aquifer, external water pressure on the grouted zone and water inflow were investigated for a subsea grouted tunnel and analytical solutions were obtained by the complex variable method (CVM), mirror image method (MIM) and axisymmetric modeling method (AMM).

Undrained analysis of ground reaction curves for deep tunnels in saturated ground considering the effect of ground reinforcement
Pengfei Li,Fan Wang,Qian Fang +2 more
TL;DR: In this article, an idealized model of an axisymmetric tunnel with an initial hydrostatic stress field was proposed to obtain the ground reaction curves by gradually decreasing the internal support pressure from the initial stress to zero after tunnel excavation.

Study of seepage field distribution and its influence on urban tunnels in water-rich regions
TL;DR: In this paper, a study of the spatial distribution of pore water pressure on urban tunnels in water-rich regions is presented, based on Harr's classical solution for unlined tunnels and the actual hydrological environment, a water pressure formula of the seepage field is derived by regarding the surrounding rock, grouting circle, lining, etc.

The study of seepage forces acting on the tunnel lining and tunnel face in shallow tunnels
In Mo Lee,Seok-Woo Nam +1 more
TL;DR: In this article, the effect of seepage forces on the tunnel face stability was studied for the case of shallow drainage-type tunnels and these results were compared with the lining stresses developed for waterproof type tunnels, and reasonable design concepts applicable to the design of tunnel lining and to the evaluation of the support pressure required for maintaining the stability of tunnel face were suggested.
