| 摘 要： | 为了探求面流消能工下游水面波动的特性，应用担丝水位计和微型计算机组成的实时数据采集和处理系统，对面流波动要素进行了量测与分析。得到了最大及最小波高、平均波高、平均周期、波高概率分布及能谱特性等波动要素。分析了不同来流（Ｆｒ数为４．７７～７．８０）条件下４种典型面流流态的平均波高的沿程分布规律，对面流表面波动的成因和减波措施作了探讨。

| Abstract: | In order to study the ave characteristics of water surface downstream of a bucket dissipator,a data sampling and processing system consisting of a tantalum-wire level gauge and a micro-computer,was used to measure and analyse various parameters of the surface currents,such as the maximum,minimum and average wave heights,the mean period,the probability distribution of wave height as well as the power spectrum.Under different flow conditions with the Froude number ranged from 4.77 to 7.80,the longitudinal average wave height distributions of four typical flow states and the factors that cause wavement were analysed.The measures to reduce the surface wavement were also discussed. |
