| 摘 要： | 高水头泄水建筑物泄水时,其固体表面必然要承受水流脉动压力作用.在其边界发生突变的部位,观测并分析脉动压力及其频率变化特性对建筑物安全运行具有一定的重要作用.本文根据东风水电站溢洪道原型观测资料,对其鼻坎脉动压力特性进行了分析,并在分析的基础上,结合模型试验资料,对已有的关于脉动压力及其频率相似性问题谈了一些自己的意见.希望能为工程设计和试验提供一点参考依据. |
| 关 键 词： | 溢洪道 脉动压力 频率 相似律 |

| Abstract: | The water flow fluctuating pressure would act on the surface of ultrarapid flow construction ,as it discharge. It is important to analyze the characteristics of flow fluctuating pressure and its frequency in the mutation position of the surface. The information about bucket fluctuating pressure from full-scal testing in Dongfeng Hydroplant spillway would be analyzed. In this paper, some ideas would be offered by constrasting the data from model testing. These results is valuable for test and design. |
| Keywords: | spillway fluctuating pressure frequency affinity law |
