Investigations of Influence of the Variation of Underground Water Levels to the Structural Performance of the Existed Subway Station

Abstract:

Based on the engineering background of Beijing unban groundwater levels rebounded, the stress behavior of subway station structure under cases of the groundwater in different water levels from the view of numerical mechanical models is researched in this paper and the working condition of this paper is the actual engineering of the Beijing subway line 10. The results demonstrate different underground water levels could lead to obvious vertical displacements, plastic changes of surrounding soil sand the groundwater level upturn obviously within a certain range make the underground structures deform and float overall. Some conclusions are important references for the further improvements of the design and construction of underground structures, reinforcement of existing substructures.
