摘要:

在纵向等效连续刚度模型的基础上,考虑环缝影响而得出修正模型,并将其应用于已建成盾构隧道长期运营过程中的安全评估。确立隧道纵向安全评估的安全体系,在运营期前提出有利于控制隧道纵向变形的方法,并在运营期对隧道的纵向安全进行合理评估。

Abstract:

A modified model is obtained on basis of the longitudinal equivalent continuous stiffness model by considering the influence of the circumferential joints. The modified model is used to assess the safety of shielddriven tunnels in their longterm operation period. The safety system of the longitudinal safety assessment of tunnels is established. The study results can be used to recommend countermeasures to control the longitudinal deformation of tunnels before they are put into operation and can also be used to assess the safety of the longitudinal deformation of tunnels during their operation stage.

Key words: Metro, shielddriven tunnel, longitudinal settlement, safety assessment
