| 摘 要： | 为保证既有地铁车站的正常运营和地下车站结构的安全，在邻近基坑开挖过程中就需要严格控制运营地铁车站结构的变形。结合上海某邻近基坑开挖的运营地铁车站，运用叠加原理，采用有限元荷载结构法和强制位移法，分别按照裂缝控制和强度控制来对车站标准段结构的稳定性及其允许变形进行分析和反算，为基坑施工提供车站结构变形的控制标准

| 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. |
