| description | The invention discloses a tunnel water inflow prediction method which comprises the following steps: based on a three-dimensional groundwater flow simulation platform, determining a simulation area range including a tunnel site area according to survey data, and establishing an equivalent continuous groundwater seepage numerical simulation model in the simulation area range; calibrating model parameters through a trial estimation-correction method and an optimization method by utilizing known or preliminarily given boundary conditions, source confluence items and underground water dynamic datain a simulation time period; and quantitatively analyzing the flow characteristics of the underground water and the water inflow of different sections during tunnel construction by using the model with the fixed utilization rate, and analyzing to obtain a water inflow source. By the adoption of the technical scheme, the tunnel water inflow of the area with uneven pore and fracture development canbe calculated, and compar |
