摘要: 本研究采用有限体积法，通过数值计算，模拟分析了行洪、蓄洪工程退洪、和分流洪水汇合的复杂流场分布，分析了洪闸附近的汇合流场结构，对比洪闸工程修建前、后的流场变化，提出流场分布特征和流速参数，重点分析汇合流场对蓄洪工程建筑物和附近大堤的影响，提出退洪区、分洪区附近的水力学指标，为洪闸布置、堤坝防护提供科学依据。
Abstract: In this study, the finite volume method was used to simulate and analyze the complex flow field distribution of flood discharge and flood discharge project, and the confluence flow field near the flood gate was analyzed. After the flow field changes, the flow field distribution characteristics and flow velocity parameters are proposed. The influence of confluent flow field on the flood storage project buildings and nearby levees is analyzed. The hydraulic indexes near the flood control area and the flood diversion area are proposed, which are the flood gate layout and dam. Protection provides a scientific basis.
