摘　　要：八字岭隧道是宜万铁路的重要控制性工程,以现场调查和试验分析为基础,研究了隧址区的岩溶发育规律;结合资料分析,研究了岩溶山区隧道施工突水灾害的等级类型,探讨了分析方法。针对八字岭隧道的工程地质和水文地质条件,研究了该隧道施工突水灾害危险地段和危险等级,为隧道施工防灾重点区段的确定提供了基础。Baziling tunnel is a key controled project of the whole Yiwan railway. Based on field investigation and test analysis, the paper firstly researches karst distributing rule of this zone, and studies grade separation of karst water bursting hazard of this tunnel construction through analyzing information, then discusses analytical methods, finally confinns the risk zone and risk grade of karst water bursting hazard of the construction through analyzing specific geological and hydrogeological conditions of Baziling tunnel, provides the basis for determining the key prevention sectors of tunnel construction.
