冻害防治长期困扰寒区隧道,传统方法主要从加强支护衬砌结构、改善防排水效果、采取保温隔热措施等几方面着手,效果仍不理想。论文通过梳理以往寒区隧道冻害防治的基础理论与工程措施,提出供热防冻是解决寒区隧道冻害问题的根本方法,并从节能、环保的角度对衬背U型供热管方法和施工缝衬背双源供热排水防冻方法进行了探讨,可供进一步研究和试验参考。
Frost damage prevention and treatment have long plagued the tunnels in the cold area. The traditional methods mainly start with strengthening the supporting lining structure, improving the drainage and drainage effect and adopting measures such as thermal insulation and thermal insulation, and the results are still unsatisfactory. In this paper, by combing the basic theories and engineering measures of freezing prevention and control of cold regions in the past, this paper puts forward that heating antifreeze is the fundamental method to solve the problem of frost damage in tunnels in cold regions. From the perspective of energy saving and environmental protection, Lining double-source heating drainage antifreeze methods were discussed for further research and test reference.
