摘要:
本文依托吉图珲客运专线五峰山隧道，运用局部存水冻胀模型，采用有限元数值模拟技术，对不同积冰位置情况下，局部存水冻胀力对隧道衬砌力学性能的影响进行了分析。研究结果表明：（1）局部存水冻胀将对隧道结构安全造成一定的不利影响，存水位置不同，影响程度有所差别；（2）积冰位置处弯矩值较未积冰时显著提高，当隧道拱顶、拱肩、拱腰处积冰时，隧道安全系数相较于无冻胀力作用时都会降低，且当拱顶处积冰时，安全系数降低更为显著。研究成果可为季冻区隧道抗冻设计及冻害整治提供参考。
Abstract:
Based on the Wufengshan Tunnel of Jituhui Passenger Dedicated Line, using the local storage water frost heave model and the finite element numerical simulation technology, this paper has analyzed the influence of the local storage water frost heave force on the mechanical properties of tunnel lining under different icing locations. The results show that the local storage water frost heave will have some adverse effects on the safety of the tunnel structure and the degree of influence varies with the different water storage location; that the bending moment value at the icing position is significantly higher than that without icing, and when the icing occurs at the vault, arch shoulder and arch waist, the safety factor of the tunnel is lower than that without the frost heave force and decreases more significantly at the vault. The research results can provide reference for the anti-freezing design and frost damage treatment of tunnels in the seasonal frozen zone.
