| 摘 要： | 水下卧倒闸门是一种适用于现代城市景观水利建设的新型闸门。采用物理模型试验的方法，对闸门在排水和引水两种工况下的脉动特性进行了深入研究和分析比较。采用加汉宁窗及线性平均的方法，对脉动信号的平稳性和幅值进行分析，得出闸门结构的自振频率，以及闸门运行时的不利工况。在排水工况下，对通气与不通气情况进行分析比较，得出通气对于闸门脉动特性的影响，为这种闸门的设计，运行管理提供参考依据。

| Abstract: | Underwater horizontal gate is a new gate adapt to modem city landscape hydraulic engineering. By physical model test, the pulsating stress characteristic of the gate had been more studied at the condition of drainage and diversion. By the method of Harming and linear average, the stabilization and range of pulsating signal had been analyzed. The selves vibration frequency of the gate and the disadvantage condition of gate operation had been discovered. In the conditions of diversion, the instances of aerate and frowst at the back of gate had been analyzed, and influence of aerate at the pulsating of erence in the design and operation of the gate. the gate had been also analyzed. It can offer a reference in the design and operation of the gate. |
