Abstract：
According to the field test results of a subway station of Beijing subway, the variations of stress and deformation such as the top plate, medium plate, bottom plate and the side walls during the construction are studied. The change characteristics of the middle pile (column) in the stress and deformation are also studied. The security of subway station and the impact on surrounding buildings are analyzed by analyzing the settlement of soil around foundation pit and the differential settlement between enclosure structure and middle pile (column) during construction.
