Abstract: The expansion of the coverage area of underground rail transit leads resulting that the construction of underground structures in many construction projects is closer to the scope of subway tunnel, which further brings about that the adjacent construction will disturb the soil around the subway tunnel and cause deformation and displacement of the tunnel structure, therefore affect the service performance. Taking the Wuhan Three Town Center Project as an example, this paper describes the automatic continuous monitoring scheme for the service behavior of subway tunnel structure for three adjacent subway constructions including TRD construction, diaphragm wall construction and MJS soil reinforcement. What's more, the paper analyzes four automatic continuous monitoring items, i.e., crown settlement, ballast bed settlement, horizontal displacement and radial convergence and finally summarizes the impact of adjacent construction on the service behavior of subway tunnel structure, which can provide a reference for the following relevant projects.
