Abstract
Excavation of foundation pit on one side and removal of load may cause differential deformation of the underground structure of adjacent subway station, and its mechanism has not been systematically understood. With reference to the engineering of a subway station in Changsha, numerical method is employed to analyze the variations of subway station structure deformation induced by excavation of adjacent deep foundation pit, and counter measures are discussed to control the deformation of subway station structure. The results show that with the increase of excavation depth, the horizontal deformation of retaining structure gradually increases, while the amplitude of deformation decreases; and the large integral rigidity of the subway station main structure functions to retain the displacement transfer of soil induced by excavation of foundation pit.关键词
