| 摘 要： | 南水北调中线总干渠在河南省安阳市穿越洪河，其交叉建筑物形式为倒虹吸，且交叉工程上游
有急流从五六渠下泄旁侧入汇。文中讨论了旁侧入汇的五六渠消力池段水跃区水流间断性问题，提出了
一种在明渠流动中简化的水跃区数值模拟方式。通过建立平面二维数学模型，对洪河交叉工程河段进行
了平面数值模拟，对交叉工程河段洪水特性进行了专题研究。模拟结果表明这种简化处理方法实用可
靠，能够反映水跃区水深共扼关系与能量损失关系，较好解决了五六渠急流入汇的水流模拟问题。

| Abstract: | The main chanel of the Mid-route of the South-to-North Water Transfer Project crosses Honghe River in Anyang of Henan Province with a crossing works of inverted siphon,where a rapid flow from Wuliu Canal laterally rushed in.The problem of flow discontinuity in the water jumping area of the stilling pool section of Wuliu Canal with a lateral inflow is discussed herein,and then a simplified mode of numerical simulation on the water jumping area within an open channel is put forward.Through establishing a 2-D ... |
