Document Type and Number:
Japanese Patent JP6652872
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a numerical analysis method of an underground water flow allowing a prompt prediction analysis with less computation load to be performed and further enabling the influence of a pressure loss inside a borehole to be considered.SOLUTION: A numerical analysis method of an underground water flow is a numerical analysis method of an underground water flow inside a ground 1 provided with boreholes 2A to 2C, and includes: a step of setting a first equation of motion for solving an underground water flow inside a water inflow zone 11; a step of setting a second equation of motion for solving the flow inside the boreholes to the Darcy's law form similar to the first equation of motion; and a step of performing the analysis of the underground water flow by employing the first and second equations of motion using an analysis mesh modeling the ground provided with the boreholes. Here, an equivalent coefficient of permeability is introduced for the purpose of expressing the second equation of motion by the form of the Darcy' law.SELECTED DRAWING: Figure 1
