本文聚焦于针对冻土区公路的融沉与冻害的防治研究,同时,透过融沉与冻害表象深刻地揭示了冻土区水场、温度场、力场的三场耦合、内聚、外张等关系。从而由对冻土区公路融沉与冻害现象的分析探析了对这双重病害的预防举措与根治方法。 This paper focuses on the prevention and treatment of thaw settlement and frost damage in permafrost regions. At the same time, through the appearance of thaw settlement and frost damage, it reveals the three coupling, cohesion and external forces of water field, temperature field and force field in permafrost regions Zhang and other relations. From the analysis of the phenomena of sinking and frostbite in the permafrost regions, this paper analyzes the precautionary measures and radical methods of this dual disease.
