摘要
本文根据南桠河三级水电站取水口前后实测含沙量和颗粒级配资料,比较了两种悬移质垂线分布计算方法。结果表明,采用罗斯公式并使用谢鉴衡修正悬浮指标计算时,入渠含沙量和颗粒级配计算值与实测值吻合,可在工程设计中使用。
Based on the measured sediment discharge and grain composition data, the two calculation methods for suspended load vertical distribution are compared in the paper. The result shows that, by calculation with H. Rouse' s formula and Xie Jianheng' s revised sus- pended index, the calculation values of sediment discharge into channel and grain composition coincides with the measured one ,which may be used in engineering design.
