阐述了带滚轮、连杆的水力自控翻板闸门的运转稳定性问题，通过水工模型试验，证明了它在运转过程中没有明显的“拍打”，说明了此种闸门能够保持其稳定性的原因，并提出了若干改善水流流态的措施，以避免或减轻闸门“拍打”现象。
The stability problem of hydraulic self-operated flap gate with roller and connecting rod is expounded. Through the hydraulic model test, it is proved that there is no obvious “flapping” during operation, which shows that the gate can maintain its stability And put forward a number of measures to improve the water flow in order to avoid or reduce the gate “beating” phenomenon.
