摘要
针对风洞子船闸下引航道口门区及连接段的通航条件,进行闸坝调度运行方式对船闸下引航道口门区及连接段的水流特性的影响研究。采用数学模型,研究风洞子航运枢纽工程闸坝开启不同位置和不同数量时下引航道口门区及连接段的水流条件。结果表明,在相同流量级时开启左岸闸门,下引航道口门区及连接段的水流条件更有利于船舶安全航行;在满足闸孔过流条件时,开启左侧闸门数量越少水流条件更有利于船舶安全航行。
Considering the navigation conditions of the entrance area in the downstream approach channel and the connecting section of the Fedongzi ship lock,we study the influence of the lock and dam dispatching mode on the flow characteristics of the entrance area and connecting section.A mathematical model is employed to study the flow conditions in the entrance area and connecting section when the lock and dam of the Fengdongzi navigation project are open in different positions and quantities.The results indicate that when the lock gates on the left bank are open at the same flow rate,the flow conditions in the entrance area and connecting section are more favorable to the safe navigation of ships;assuming the discharge condition of lock gates is met,the flow conditions are better when fewer lock gates on the left bank are open.
