With the increasing requirements for the construction of long and deep buried tunnel, the water inrush caused by tunnel water inrush often occurs, which causes the damage of equipment, delays the construction period, and damages the stability of the tunnel, leading to surface subsidence and collapse, resulting in casualties. Firstly, the water bursting process of karst tunnel, the influence of water body on Karst flood and the characteristics of water bursting are analyzed. Secondly, the analysis of Yesanguan Tunnel on Yichang Wanzhou railway treatment method and flood monitoring data interpretation method can reduced water inrush cavity detection test proved the effect is good. Finally, the understanding of the mechanism of water inrush disaster and the matters needing attention are summarized, and the relevant analysis can provide reference for other karst flood treatment.
