山区河流航电枢纽最大通航流量研究

针对山区河流航电枢纽建设后实际最大通航流量无法满足规范要求的问题,对山区河流航电枢纽布置后的最大通航流量进行研究。依托东风岩航电枢纽,采用物理模型试验等方法,结合东风岩枢纽通航水流条件模型试验和船模试验分析船闸上、下引航道口门区及连接段水流条件和通航条件,从而对东风岩航电枢纽安全通行的最大通航流量提出建议,并提出山区河流中低水头航电枢纽最大通航流量不应低于天然情况下该河段的禁航流量等结论。该研究成果可为山区河流中低水头航电枢纽最大通航流量的确定提供借鉴。

Study on the maximum navigable flow of navigation power junction in mountainous rivers

In view of the problem that the actual maximum navigable flow after the construction of the navigation and power junction in mountainous rivers can t meet the requirement of the code,we study the maximum navigable flow after the arrangement of the navigation and power junction in mountainous rivers.Based on the Dongfengyan navigation power junction,we analyze the flow and navigation conditions of the entrance area and the connecting section of the upper and lower approach channels of the ship lock by means of physical model test and ship model test,and put forward suggestions on the maximum navigation flow for safe navigation of Dongfengyan navigation power junction,and come to the conclusion that the maximum navigable flow of the medium-low-head hydro junction in the mountainous river should not be lower than the forbidden flow of the natural river.The research results may serve as a reference in the determination of the maximum navigable flow of the middle-low-head hydro junction in mountainous rivers.
