Abstract
Based on the engineering background of Beijing urban groundwater levels rebounded, the stress behavior of a subway station structure under cases of the groundwater in different water levels from the view of numerical mechanical models is researched in this paper. The working condition of this paper is the actual engineering of the Beijing subway line 10. The results demonstrate that different underground water levels could lead to obvious vertical displacements and vertical stress changes of structures. The groundwater level upturn (obviously, within a certain range) could make the underground structures deform and float overall. Indeed, it could cause craze, water seepage, harmful ion erosion, and a series of problems resulting in influence on the durability of structures. Some conclusions are important references for further improvement of the design and construction of underground structures and reinforcement of existing substructures.
