| 摘 要： | 造成高寒地区隧道冻害的原因有很多方面，如衬砌混凝土的冰冻破坏、局部存水冻胀破坏以及既有裂缝裂隙水的冻胀破坏等。以鹧鸪山隧道为工程背景，通过有限元软件ANSYS对隧道衬砌背后局部存水冻胀产生的应力进行计算分析，说明这种局部存水空间冻胀对隧道衬砌可能造成破坏原因，为寒区隧道的抗防冻措施提供理论依据。

| Abstract: | Some reasons such as frost-damage to lining, local frost-damage by sealed water and frost-damage by fracture water, etc. , can damage the tunnel in cold regions. Based on the geological conditions of Zhegushan tunnel, frost-damage stress caused by local water-sealed is simulated using finite element program ANSYS. Some reasons are presented about this damage, which can act as theoretic basis for the frost protection measures of the tunnel in cold regions. |
