摘　　要：由于枢纽船闸引航道口门区特殊的水流结构,口门区泥沙淤积问题是影响河流船闸正常运行的一个重要问题。针对枢纽船闸引航道口门区三维水流的结构特点,开发了可高效高精度模拟该区域水流结构的完全三维非静压数学模型,对其水流结构特征进行了分析和研究,从消除回流和归顺口门区航行水流的角度,提出了可有效减缓引航道口门区泥沙淤积问题的工程措施,为枢纽通航运能提升和船舶安全高效运营提供技术支撑。Because of the special flow structure in the entrance area of the approach channel of the hub ship lock,the sediment deposition in the entrance area is still an important problem affecting the normal operation of the river ship lock.According to the structural characteristics of the three-dimensional flow in the entrance area of the approach channel of the hub ship lock,a complete three-dimensional non hydrostatic mathematical model which can simulate the flow structure in this area with high efficiency and high precision is developed.The characteristics of its flow structure are analyzed and studied.From the perspective of eliminating the backflow and the navigation flow in the return gate area,the engineering measures that can effectively slow down the sediment deposition in the gate area of the approach channel are put forward,so as to provide technical support for the improvement of the navigation energy of the hub and the safe and efficient operation of ships.
