The invention discloses a three-dimensional numerical
simulation method for hydraulic characteristics of a
uranium tailing pond flood drainage
system. The method comprises the following steps: collecting, analyzing and checking basic data of the
uranium tailing pond flood drainage
system; selecting suitable numerical
simulation software; establishing a three-dimensional numerical model of the
tailings pond flood drainage
system and dividing grids according to regions; boundary conditions of an inlet and an outlet of the
uranium tailing pond flood drainage system are determined; carrying out numerical
simulation by adopting a model subjected to
experimental research, comparing with a
model test result, and verifying, calibrating and optimizing a numerical model according to a comparison result; performing three-dimensional numerical simulation on the uranium tailing pond flood drainage system; and related data of the drainage capacity, the wall
surface pressure, the
water flow velocity,the
water depth and the flow state of the uranium tailing pond flood drainage system are given. By establishing the three-dimensional numerical model of the uranium tailing pond flood drainage system, the
scale effect of a
model test does not need to be considered, the limitation of a theoretical formula method in the aspects of arrangement mode and structural size of the flood drainage system issolved, and the method is low in cost, short in period and high in simulation precision.
