Application of 2D Flow Mathematical Model in Flood Control Evaluation of Tongjiang River Bridge

Cen Wen

Abstract

It is necessary to evaluate the impact on flood control of a river-crossing bridge.To evaluate the influence on the flood control after Tongjiang River Bridge is built,a two-dimensional flow mathematical model based on unstructured grids has been built and tested.The model is adopted to simulate the flow in the engineering reach of Tongjiang River Bridge,and the simulation results show that the influence of the proposed bridge on flood control and flow characteristics is unconspicuous,thus to provide a strong scientific basis for the approval and construction of the project.
