摘要
对寒区隧道传统的冻害防治技术进行了分析和总结,介绍了衬背设置U型供热管技术、洞内地热能供热防冻技术和衬背双源供热防冻新技术,认为供热防冻是解决隧道冻害的根本途径,可供寒区隧道防冻设计施工及进一步的试验研究参考。
Traditional prevention and cure techniques of frost injury to cold region tunnels are analyzed and concluded,which provides references for freeze-proofing design construction of cold region tunnels and further experimental study.
