摘　　要：以西藏米拉山口5790m特长隧道为实际案例,通过分析当前常用的隧道防冻技术,对米拉山特长隧道的防冻害提出了综合保温设计。设计中采用了阳光棚、保温室、空气幕技术、PTC元件以及空气交换机等综合措施,可以有效的减少隧道对外的热交换,达到保温防冻的效果。通过本文的分析探讨,可以为米拉山隧道建设提供理论参考,可以为今后西藏地区隧道建设提供理论基础与技术支撑。In this paper, a comprehensive thermal insulation design of the anti freezing injury of Mila＇s mountain specialty tunnel is proposed by analyzing the current commonly used tunnel freezing technology in Tibet, which is a practical case of Mila mountain tunnel 5790m. In the design, the comprehensive measures such as sunshine shed, air curtain, air curtain, PTC element and air switch can effectively reduce the heat exchange of tunnel, and achieve the effect of heat preservation and freezing. Through the analysis of this paper, it can provide a theoretical reference for the construction of Mila mountain tunnel, which can provide theoretical basis and technical support for the construction of tunnel in Tibet.
