英文摘要	According to segment's actual structure of shield tunnel in Shanghai, longitudinal deformation's development and characteristics based on segment dislocation mode are analyzed for shield tunnel. Bolt shear model and bolt tensile model are established on the basis of this and the corresponding formulas are deduced to discuss connecting bolt's stress and deformation. The results show that for bolt shear model when bolt stress reaches shear strength design value, the dislocation value between the adjacent segments is 7.2mm without considering segment convex tenon and concave tenon's occlusal effect. For bolt tensile model without considering concrete segment's tensile deformation, when the dislocation value reaches 4.93mm, bolt stress is 640Mpa which is the bolt's yield strength value; when the dislocation value reaches 19mm (convex tenon will leave concave tenon), bolt stress is 730Mpa; when the dislocation value reaches 8.5mm, the joints opening value is 6mm, which is the waterproof control standard for tunnel. The subway tunnel's structure safety should be controlled from the perspective of waterproof.; Geosciences, Multidisciplinary; Meteorology & Atmospheric Sciences; Water Resources; SCI(E); 0; ARTICLE; 4; 1447-1451; 5
