Abstract：Predicting the water inrush disasters is of great importance in the construction of deeply buried tunnels.The geological background of the proposed Zhangjiawan tunnel is complicated,and accurate prediction of the water nrush disasters in the tunnel is helpful to guide the construction.In this paper,based on the analysis of the karst hydrogeological conditions in the tunnel site area,the water inflow of Zhangjiawan tunnel was calculated through groundwater dynamics and numerical simulation,and the analytical method was used to predict influence range and analyze the influence on groundwater environment.The results showed that the water inflow was 66 390 m3/d,and the water inrush phenomenon was mainly concentrated in the deeply buried karst section and fault fracture zone.Within the influence radius,the flow of spring point was greatly reduced and the quality of the groundwater environment was reduced.
