摘　　要：为验证北河桥闸工程初步设计方案的合理性,依托1∶100的水工整体模型,对现状河床工程的行洪能力、通航条件、消能防冲及闸门调度等内容进行试验研究。试验结果表明,闸门敞泄时河道水流基本顺直,满足安全运行的要求,但上下游引航道口门区水流条件及下游口门区的横向流速均不满足通航要求,需对其进行优化。试验成果可供设计参考。In order to verify the rationality of Beihe bridge-gate project’s preliminary design,a hydraulic model test is conducted based on the hydraulic model with 1∶100.The test items include the discharge capability,navigation condition,energy dissipation and erosion control,gate operation,etc.The experiments show that the stream flow is straight and can meet the requirements of safety operation in the condition of the gate opening completely,but the flow condition of the up-downstream approach entrance area and the transverse flow velocity around the downstream entrance area cannot meet the navigation requirements,so,both of the above-mentioned conditions should be optimized.The results of the test can be used for the design of similar projects.
