Shield tunnel is more and more widely used in urban underground traffic construction in soft soils and urban cities along with the fast development of urban traffic engineering. However, the progress and development of shield tunnel construction cannot radically avoid the surface subsidence. The paper analyzed the magnitude of surface subsidence and deformation rules in different stages owing to the construction of shield tunnel super-large diameter slurry based on the in-situ monitoring data from a current project in Shanghai. It finally carried out the contract analysis of measured data and calculated results.
