摘要: 从优化闸门结构形式入手,进一步研究了闸门的减振措施。对闸门优化方案的1/20全水弹性模型进行了流激振动试验,检验优化方案的减振效果,并评估了其方案对闸门动力特性的影响。试验结果表明,闸门的优化方案使减振效果十分显著,可供其他类似的潜孔式闸门借鉴。

Abstract: This study is a deepening of cognition and supplement to the research contents on radial gates installed at the TGP divesion bottom outlets for "Ninth Five-year-plan" science technology key-tackling items of our country. The vibration diminishing measures for gates were further studied by optimizing their structural configuration. The flow-induced vibration tests for the optimum alternative were conducted on a full hydroelastic model with scale 1∶20, for estimating the vibrationdi-minishing effect and assessing its influences on dynamic properties of the gates. The test results showed that the vibration-diminishing effect of the optimum alternative is obvious, and these results may be used as reference for similar submerged-outlet gates.
