DYNAMIC PROPERTY ANALYSIS ON JOINT FOR SUBMERGED TUNNEL UNDER EARTHQUAKE
地震作用下沉管隧道接头力学性能分析

Based on the mathematical model for analyzing the earthquake response of submerged tunnel,the analytical model for the Nanjing Changjiang Tunnel is proposed. The comparative calculation of dynamic property of the tunnel joint is completed under the condition of rigid joint,hinged joint,elastic joint and so on. It is shown that the change of dynamic modulus of elasticity and modulus of resistance of ground may affect the dynamic property of the tunnel joint.
