摘　　要：结合拉西瓦水电站导流洞１∶１００的水工单体模型，利用先进的噪声量测系统，对竖井进流水平旋转内消能泄水道的空化特性进行了减压模型量测，显示与分析了该种泄水道空化噪声的基本特征以及上下游水位、通气状态、泄量及压力对其空化特性的影响，讨论了这种泄水道空化的原因，并在对比试验的基础上提出减免该种泄水道空化的措施．The cavitation characteristics of the sluiceway of horizontal vortex flow inner energy dissipater wwith shaft inlet are investigated with the noise detector.The basic characteristics of cavitation noise,the effect of upstream and downstream level,aeration condition,discharge and pressure are analyzed.The cause of cavitation are discussed and the measure for mitigation are suggested.
