摘要
根据沉管隧道地震反应分析的数学模型,建立了南京长江隧道的离散化分析模型,就管段刚性连接、铰接和弹性连接等3种情况对该隧道接头的动力性能进行了比较计算。分析了地基动弹模、地基抗力系数的变化对管段接头力学性能的影响。
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.
