Abstract: Structure displacement of the running metro station caused by adjacent foundation construction should be controlled strictly so as to keep the normal operation of the existing metro station and guarantee the security of the existing station structure. Based on the running metro station adjacent to foundation excavation in Shanghai, by superposition principle and load-structure method of FEM and forced displacement method, the stability and permissible deformation of the standard station structure are analyzed and back-calculated according to the mode of fracture control and strength control separately. The result can be used to the standard for deformation control of station structure on foundation pit construction

Key words: metro station, structure, forced displacement method, deformation control
