Summary:The southern section of Gouzhigou tunnel, which is in the pipeline project of the natural gas transmission from the western to the eastern region, is located in the medium mountain canyon area in the northern Tianshan fold belt, Xinjiang. The physical geography and geological environment conditions at the tunnel project area are complex. After a field survey, the geological hidden trouble in the project area mainly are unstable rock and collapses at the cave entrance, unstable slopes, abandoned slag slopes and the stability of surrounding rocks. In this paper, the distribution, size and characteristics of the geological hazards are described. The risks of the hazards and the impacts of the tunnel construction safety are analyzed. At last based on the evaluation results of geological security, prevention measures are put forward to remove or weaken the geologic hidden trouble.
