摘　　要：地铁隧道常发生涌水涌泥事故,涌水涌泥具有难预测、破坏性强的特点,既造成经济损失,也构成严重安全隐患。通过总结地铁隧道在施工和运营期间发生的涌水涌沙事故案例,对地铁隧道突涌水事故的致灾风险源、失稳破坏形式以及事故危害等级进行划分和分析,为隧道涌水涌沙诱发机理研究和防治措施的设计提供参考依据。Water and mud inrush accidents often occur in metro tunnels,which are difficult to predict and highly destructive.It not only causes economic loss but also brings the potential safety hazard.By summarizing the cases of water and sand inrush accidents that occurred during the construction and operation of metro tunnels,the disaster risk sources,instability failure modes,and accident hazard levels of sudden water inrush accidents in metro tunnels are classified and analyzed,so as to provide the reference basis for the research on the mechanism of water and sand inrush in tunnels and the design of prevention and control measures.
