Conference paper


Segments floating is often encountered during the large-diameter shield tunneling. Shearing resistance of circumferential joints is of great importance for resisting the tunnel floating. The shearing resistance in terms of circumferential joint dislocation is studied using 3D numerical simulation. The influences of bolt types, gaskets, transmission cushions, and longitude bolt pre-force on the shearing resistance are investigated, respectively. The simulation results indicate that the dislocation process of circumferential joint can be divided into three stages, and the friction force between transmission cushion and concrete mainly determines the shear resistance of segment joint in the first stage, then in the last two stages, bolts contact the bolt holes and perform shear ability which varies from the bolt type. Based on the results, the safety and durability of circumferential joint are discussed. Some suggestions of shearing resistance design of lining structure are presented.
