摘要

昆仑山隧道是青藏铁路550 km连续多年冻土区最长的高原冻土隧道。在高寒缺氧、低气压地区修建铁路隧道所遇到的是全新的技术难题。室内和现场试验及施工结果表明：在多年冻土隧道施工中采用湿喷混凝土支护，使混凝土与冻土围岩黏结牢固，并能保证支护混凝土的质量，证明湿喷混凝土支护在高原多年冻土区隧道施工中是可行的。

Abstract

The Kunlunshan Tunnel is the longest tunnel of Qinghai-Tibet Railway on 550km continuous permafrost. It is the new technical problems met with during construction of tunnel in the area of plateau

cold and low atmospheric pressure. The result of the indoor and field experiments and construction practice showed that when wet concrete shot technology has been used in construction of permafrost tunnel

shot concrete could be felt with frozen wall rock firm and the timbering quality of the tunnel could be assured. It has been proved that wet shot concrete could be used in the construction of tunnel in plateau permafrost.
