摘　　要：科学可行的隧道涌突水评价模型应准确客观地描述隧道重点部位的涌水特征,同时也能够反应出涌突水灾害本身的不稳定性。以弥玉高速公路登楼山隧道1#斜井穿越复杂断块山区为工程背景,在野外调查与水文地质分析基础上,选定了控制隧道涌突水灾害的7个指标,结合突变级数法构建了适用于断块结构区域隧道涌突水灾害的风险评价模型,并引入本研究团队已提出的评价体系,将二者应用于隧道斜井工程的涌突水分段风险评价中,并与实际施工涌水情况对比验证。结果表明:基于突变级数法构建的涌突水灾害评价模型在断块结构地区相较于既有评价体系具有更好的适用性与准确性。研究成果可有效指导登楼山隧道主洞施工的水害防治工作,评价模型可为复杂山区富水隧道的涌突水灾害风险预测提供参考。A scientific and feasible assessment model of water inrush in tunnel should be able to describe the water inrush characteristics of key parts of tunnel accurately and objectively,and it can also reflect the instability of water inrush disaster.Based on field investigation and hydrogeological analysis,the 1#inclined shaft of Dengloushan tunnel of Miyu Expressway was taken as the engineering background,based on field investigations and hydrogeological analysis,and seven assessment indexes that determine the occurrence of tunnel water inrush disaster was selected to construct the risk assessment model suitable for water inrush disaster of tunnel in fault block structure area combined with catastrophe series method.The article also utilized the existing assessment system proposed by the research team.Both methods were applied to assess the risk of water inrush in a tunnel inclined shaft project.Finally,the two assessment model results were verified and compared with the actual construction of the tunnel excavation water gushing situation.The results showed that:The assessment model of water inrush disaster based on catastrophe progression method has better applicability and accuracy than the existing assessment system in fault block structure area.The research results can effectively guide the prevention and control of water damage in the main tunnel construction of Dengloushan Tunnel.The theoretical assessment model can be extended to the risk prediction of water inrush disaster of water-rich tunnel in complex mountainous areas.
