摘要
基于黄河下游泥沙观测数据,采用B C科诺罗兹公式、瓦斯普公式、何武全经验公式和张英普经验公式,计算并分析不淤流速。结果表明,管道输水不淤流速的上限为何武全经验公式,下限为B C科诺罗兹公式;工程设计中可采用瓦斯普或张英普经验公式,计算不淤流速。
Based on the observed data of the Yellow River silt downstream, the non-silting velocities were calculated and analysed by experience formula, Wasp experience formula, Wuquan He experience formula and Yingpu Zhang experience formula. The results showed that Wuquan He experience formula was suit- able to calculate the upper limit of pipeline non-silting velocity, and B C experience formula was suitable for lower limit. Wasp and Yingpu Zhang experience formulae could be used to calculate the non-silting ve- locity in engineering design.
