Abstract：The environment is very special at Galongla extra-long tunnel of Zhamu—Motuo highway in Tibet. The terrain，geology，earthquake and meteorological conditions in this region are representative compared with other cold plateau tunnels. The survey and design of this tunnel are combined with satellite remote sensing，in-situ survey，laboratory and field tests，theoretical analysis，numerical simulation，real-time monitoring and so on. From the idea of environmental protection，ecological balance and green development，several key techniques are proposed，that is，(1) frost heave mechanism and insulation technology in cold region tunnel；and (2) earthquake damage mechanism and aseismic technology in high intensity earthquake zone. These proposed key techniques have great significance for tunnel construction in Qinghai—Tibet Plateau with modern glacier.
