摘　　要：对西气东输二线工程新疆果子沟段某隧道南口进行实地调查,查明隧道工程区及其周围的自然地理、地质环境条件,同时调查隧道工程区存在的地质隐患类型、分布、规模、危险状态等因素,分析评价其对隧道施工安全的影响,最终根据地质安全评价结果,提出消除或减弱地质隐患的防治对策和建议。The Second Line Project of West-east Gas Transmission is a northwest corridor for gas import, and it is important in the distribution of gas pipe network. In this paper, field investigation is done on Section Guozigou of the tunnel in Second Line Project of West-east Gas Transmission. The physical geography and geological environmental conditions of the project area and its surrounding are found out. The type, distribution, scale and dangerous state of geologic hidden trouble are investigated. And the influence on construction safety is evaluated. At last, based on the evaluation results of geological security, prevention measures are put forward to remove or weaken the geologic hidden trouble.
