摘要：
To investigate the ultimate bearing capacity of the stagger-jointed shield tunnel structure reinforced by steel plate in soft soil areas, a full-scale experimental test is carried out on the three rings of the steel plate reinforced shield tunnel. The convergence deformation, structural internal force, and the peeling conditions of the tunnel and the steel plate is obtained. The conclusions are as follows: The peeling between the steel plate and the tunnel segment is the main form of the damage of the reinforced structure, which occurs mainly near the tunnel capping block. When the steel plates at four positions are peeled off, the reinforced tunnel structure enters the yield stage. The research results of this paper provide a reference for the reinforcement of the stagger-jointed shield tunnels in the soft soil areas in the future.
