Formation water pressure and seepage volume in front of excavation face are important parameters of underwater tunnel projects, and also key indexes for designing the support force of excavation face and advanced water blocking and reinforcement parameters. Firstly, in view of the limitation in analyzing the 3D seepage field in front of the excavation face of underwater tunnels with the previous 2D seepage model, when building the three-dimensional seepage analytical model of the underwater tunnel, the seepage equipotential surface in front of the excavation face is considered as the space surface. Secondly, with the plane of the excavation surface as the boundary, the distribution function of water head in the half stratum space of all unexcavated areas is deduced to derive the calculation formulas of water seepage at the excavation face and pore water pressure in the front formation. Finally, the influence of factors on the water pressure and seepage in front of excavation face is analyzed, such as advanced reinforcement thickness and the relative value of permeability coefficient between soil and advanced reinforcement. The results show that, compared with the previous theoretical model of 2D seepage field in front of excavation face, the 3D analytical model can better reflect the spatial seepage pattern in front of excavation face, and the error between the calculation results of water inflow and water pressure is less than 5%; when the reinforcement range in front of excavation face is twice the tunnel diameter, and the relative permeability coefficient between the advanced reinforcement area and the stratum is set as 50, which is a safe and reasonable parameter for advanced water blocking and reinforcement.
