摘　　要：如何在隧道中采取行之有效的冻害防治措施,保证安全运营,是当前隧道工程界迫切需要解决的问题。笔者针对寒区隧道的冻害防治技术之一——保温隔热材料防冻措施,提出玻化微珠保温砂浆隔热结构体系,用玻化微珠保温砂浆隔热层代替原来的有机保温材料隔热层,通过保温砂浆试验研究与隔热层结构设计计算,进一步达到隧道保温防冻技术的要求。How to take effective prevention measures on frost damage, this issue urgently needs to be solved in engineering. For thermal insulation method, which is one of damage preven- tion technologies in cold region tunnels, this paper proposes the intermediate insulation layer structure with glazed hollow beads insulation mortar. That is, the glazed hollow beads insulation mortar is used as insulation layer to reach antifreeze design goals, instead of original organic insu- lation materials. The experimental study of insulation mortar and the calculation of the insulation layer structure have been carried out to reach the requirements of frost prevention technology in cold region tunnels.
