Abstract
Based on the conformal mapping of the complex variable methods, analytical solutions for water inflow into an underwater tunnel are derived for a constant hydraulic head, constant water pressure and constant hydraulic head as well as grouting ring boundary condition at the tunnel perimeter. According to the proposed formula, relation between water inflow and h/2r, as well as grouting ring thickness, some valuable conclusions are proposed.
