西江航道整治工程中的数值模型研究和应用 Study and Application of the Numerical Simulation of the Channel Regulation Project in Xijiang River

以西江四滩河道整治工程为例，建立了航道整治工程数值模型，模型采用正交贴体网格，耦合求解水动力场和悬移质浓度场，数值模拟了工程前后的流场变化和河床冲淤过程。经校准后，模拟效果较好，可以为整治工程提供定量预测，并为今后类似工作提供借鉴。 A model of Xijiang channel regulation project was developed, which used the curvilinear and orthogonal coordinate system, the primitive variable and suspended sediment concentration field was simulated by coupling method. After the model was calibrated, the modeling effect was good. The model constructed here is a powerful tool for those similar projects.
