ABSTRACT
ABSTRACT: The long-term effect of groundwater seepage and seepage tunnel lining partially flooded on upper surface construction and road is an unavoidable problem for urban underground space development. By establishing the Finite Element Model (FEM) for tunnel lining partially flooded in seepage field, surface subsidence is analyzed in four situations, namely different lining parts, different permeability ratio, different tunnel depth with the same underground water level and different underground water level with the same tunnel depth. The laws of surface subsidence and stability time are gained, which give guide to construction and post-surface subsidence monitoring in practice.
