摘　　要：突涌水是岩溶地区隧道施工过程中最常见的地质灾害,具有强复杂性和破坏性,已成为隧道建设中面临的主要挑战之一。以岩溶地区隧道突涌水发生机理为基础,对突涌水灾害类型进行了分类,总结了裂隙型、断层型、溶洞溶腔型灾害类型下,岩溶隧道突涌水的发生条件、演变规律和灾变力学分析模型;分析总结了三种典型灾害类型下岩溶隧道突涌水最小岩盘防突厚度计算公式及时适用范围,提出岩盘防突厚度是判断岩溶隧道突涌水发生的重要指标。对目前岩溶隧道突涌水机理进行了展望,认为突涌水力学分析模型应进一步准确表征围岩实际受力状态和工程地质条件。论文综述成果为深入研究岩溶地区隧道突涌水灾害发生机理,了解突涌水致灾机理研究难点和今后的发展方向提供了参考。Water inrush is the most common geological disaster during the tunnel construction in Karst regions.It is highly complex and destructive,and has been one of the main challenges in tunnel construction.Based on the occurrence mechanism of water inrush of tunnels in Karst regions,this paper first classifies the water inrush disaster types and summarizes the occurrence conditions,evolution laws and catastrophe mechanics analysis model of water inrush in Karst tunnels under the disaster types of fracture,fault and Karst cavity;then this work analyzes and summarizes the calculation formula of the minimum rock disc outburst prevention thickness of water inrush under these three typical disaster types,and proposes that the rock disc outburst prevention thickness is an important index to judge the occurrence of water inrush in Karst tunnel.The paper finally reviews the present studies on the mechanism of water inrush in Karst tunnels and suggests that the hydraulic analysis model of inrush should further accurately characterize the actual stress state and engineering geological conditions of surrounding rocks.The results of this review provide a reference for deeply investigating the occurrence mechanism of water inrush disasters of tunnels in Karst regions to understand the difficulties and future development directions of the studies of water inrush disaster mechanisms.
