| 摘要： | The composite segment has been used in the shield tunnels of the subway, underground road, underground pedestrian passage and under ground reservoir, etc.However, the mechanical behavior of the composite segment is not clarified, because the structural type is complicated Meanwhile, the selected structure model and parameters are not reasonable Therefore, the designed composite segment lining of a shield tunnel has the disadvantages of safety and economy.The stiffness reduction method is proposed for considering confined effect, interface slip, local buckling and damage The proposed design method can be used to solve the coupling of multi-material and composite segment under multi-material and multi-scale, and are suitable for a rational design of the composite segment because of avoiding the convergence of computations and having high degree of precision and clear physical meaning. |
