摘　　要：结合青藏铁路多年冻土隧道的设计,通过对多年冻土特殊性、寒区隧道病害及冻胀机理的分析,提出了多年冻土隧道设计中应用隔热保温技术的思路。Combined with the design of tunnels in permafrost regions of the Qinghai-Tibet Railway, the features and frost heave mechanics of perma-frost and the troubles to tunnels in cold regions are analyzed in this paper. The idea of application of thermal isolation technique to tunnels in perma-frost is also proposed.
