我国东部平原地区,有许多低水头的水闸。其中有的水闸在泄流过程中引起闸门振动。经统计,江苏省有23座闸曾发生过闸门振动,其中弧形闸门有14座。江苏的嶂山闸;山东的韩庄闸都曾发生过较为强烈的闸门振动。这些水闸在闸门振动时,水头都处于2—5米,闸门的开度大多在0.1—0.6米之间。国外也有许多低水头水闸的闸门发生强烈的振动。美国有几座弧形闸门发生过较强烈的振动,有的闸门振动甚至导致构件开裂。这些闸门振动都处在5英尺或稍大的水头下,闸门为小开度。如临哥耳德弃水道的宽20英尺,高22英尺的弧形闸门,过水时以5赫的频率振动,变形达1/4英寸,因之构件断裂严重。它的垂直振动也很强烈,致使一根钢丝绳吊索破坏。此外日本、巴基斯坦都曾出现由于闸门振动而引起闸
There are many sluice gates in the eastern plains of our country. Some of these sluices cause the gate to vibrate during discharge. According to the statistics, there are 23 gates in Jiangsu Province that have been subjected to gate vibration, of which 14 are arc gates. Cangshan Gate in Jiangsu Province; Hanzhuang Gate in Shandong Province have had a relatively strong gate vibration. These sluices in the gate vibration, the head are at 2-5 meters, most of the gate opening between 0.1-0.6 meters. There are also many sluice gates outside of China where there is strong vibration. In the United States, there are some more severe vibration occurred in the radial gate. Some of the gate vibration even cause the components to crack. These gates vibrate at 5 feet or slightly above the head, with a small opening. The 20-foot-wide and 22-foot-arc gates, like the Göteger Abandoned Waterway, vibrate 5 Hz over the water and deform up to 1/4-in. Its vertical vibration is also very strong, resulting in the destruction of a rope sling. In addition, Japan and Pakistan have all caused gates due to gate vibration
