摘　　要：利用长河段一维数学模型,预报了大顶子山航电枢纽在运行不同时期后的冲刷深度及水位降落情况。结合近坝段河床防护措施,确定了大顶子山枢纽下游最低通航流量、相应的下游最低通航水位、枢纽船闸的门槛最小水深以及船闸下闸首底槛的高程。Based on a one-dimensional mathematical model of the long river reach,the fall of level and the scour depth of Dadingzishan Navigation-power Junction during different operation periods were predicted in this paper.Combining with protective measures of the riverbed near the dam,the minimum navigable discharge of the Dadingzishan Navigation-power Junction,the lowest navigable stage at downstream of the junction,the minimum water depth on sill and the sill elevation of the lower lock head of the ship lock were also determined.
