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.

Key words: plateau permafrost, tunnel, timbering technique, technology, experiment research
