摘　　要：首先介绍了成都-昆明铁路秀宁隧道水文地质条件和区域构造环境,依据地下水含水岩组的富水特性、地下水的补径排特征,划分隧址区的水文地质单元。然后结合隧道施工时涌水状况、开挖揭示的地质情况,分析了汤郎-易门深大活动断裂影响下隧道涌水来源及其与地表水体的水力联系,进而预测地下水涌水量。最后对隧道不同区段涌突水的危险性作出评价。The hydrogeological conditions and regional tectonic environment of Xiuning tunnel in Chengdu-Kunmingrailway were introduced firstly. According to the water rich characteristics of groundwater aquifer system and thecharacteristics of groundwater recharge,runoff and discharge,the hydrogeological units of the tunnel site were divided.Combining with the water gushing condition during the tunnel construction and the geological condition revealed byexcavation,the paper analyzed the water gushing source of the tunnel and its hydraulic connection with the surfacewater under the influence of Tanglang-Yimen deep active fault,and then predicted the water gushing amount of theunderground water. Finally,the risk of water gushing in different sections of the tunnel was evaluated.
