    • Abstract
  • As a new type of construction process, the mechanical connection channel is welded by steel plate, and the welding process is prone to fatigue damage under dynamic loads. According to the problem of the joint, the acceleration response, displacement response and communication channel under different connection modes are studied by using the finite element simulation. For the displacement response semi-rigid connection, the joint can absorb part of the displacement transmission, which is beneficial to the safety of the overall structure of the tunnel. The rigid joint is more integral and the displacement does not suddenly drop. The semi-rigid joint can weaken the transmission of acceleration, while the rigidity of the rigid joint is strong, and the acceleration transmission efficiency is high.
