高寒地区隧道的冻害机理综述

On the Frost Action Mechanism of Tunnels in Severe Cold Districts

简述衬砌混凝土的冰冻破坏、局部存水冻胀破坏、冻胀性围岩冻胀破坏以及既有裂缝裂隙水的冻胀破坏等因素对高寒地区隧道的冻害机理。

This paper mainly analyses some factors such as frost damage on lining concrete, frost heaving damage caused by partial accumulated water, frost heaving damage on surrounding rock and frost heaving damage caused by existing fissure water on the frost action mechanism of tunnels in severe cold districts.
