建立了焦港三角门船闸物理模型。通过模型试验研究开通闸运行条件下闸门启闭机的受力,确定启闭机受力能满足开通闸要求的临界控制条件。控制条件分别为:上游高水位控制时,能进行开通闸运行的临界上下游初始水位差应小于0.39 m;上游中水位控制时,能进行开通闸的临界上下游初始水位差应小于-0.34~0.38 m;上游低水位控制时,能进行开通闸的临界上下游初始水位差应小于-0.37~0.43 m。三角闸门开关门的受力变化规律可为开通闸运行研究提供参考。
建立瞭焦港三角門船閘物理模型。通過模型試驗研究開通閘運行條件下閘門啟閉機的受力,確定啟閉機受力能滿足開通閘要求的臨界控製條件。控製條件分彆為:上遊高水位控製時,能進行開通閘運行的臨界上下遊初始水位差應小于0.39 m;上遊中水位控製時,能進行開通閘的臨界上下遊初始水位差應小于-0.34~0.38 m;上遊低水位控製時,能進行開通閘的臨界上下遊初始水位差應小于-0.37~0.43 m。三角閘門開關門的受力變化規律可為開通閘運行研究提供參攷。

A physical model on Jiaogang ship lock is set up, and the force of sluice gate hoist is studied by the model. The results show that the upper and down sluice gate can be opened in the same time in the following conditions:1) The original tide range is less than 0.39 m when upstream water stage is 3.71 m;2) The original tide range is from-0.34 m to 0.38 m when the upstream water stage is 1.64 m;3) The original tide range is from-0.37 m to 0.43 m when the upstream water stage is 0.96 m. The force variation law of sluice gate hoist provides reference for the similar study.
