高寒隧道隔热层防冻法的分析研究

摘要

Based on the problem easy to produce freeze injury building tunnel in the region of alpine, through analyzing and studing the different installation methods of insulating layer, and laboratory test of mural type heat preservation bushing structure, put fo%针对在高寒地区修建隧道容易产生冻害的问题,通过对隔热层不同敷设方式的分析研究,以及离壁式保温衬套结构的室内试验,提出了高寒隧道隔热层防冻法的敷设结构形式,为高寒地区隧道施工提供了一种新的抗冻措施。
