摘要
针对高寒地区隧道内冻融、冻胀现象严重,容易使衬砌混凝土产生开裂、酥松、剥落、挂冰等危害,通过对隧道保温层与衬砌的紧密性粘结及安装施工技术进行研究,采用结构保温技术,成功的解决了高原高寒隧道的冻害问题。
Frost thawing and frost heaving in tunnel are serious in frigid plateau region, which will easily lead to a series of hazards including masonry concrete cracking, crisping, exfoliation, and icing and so on. The essay studies tightly binding between tunnel insulation layer and lin ing and installation technology, adopts structural insulation technique, and successfully solves tunnel freezing harmful in frigid plateau.
