摘要

中文摘要: 研究了宽尾墩位置、始扩点水流佛汝德数与堰上水头之间的关系，导出了与水头损失、闸门宽度有关的计算公式。搜集了国内多个电站的宽尾墩体型参数及相关水力参数进行计算，结果表明，始扩点水流佛汝德数分布在1.7~2.3之间，平均值为2.042。结合实际工程，讨论了移动宽尾墩位置对水力特性的影响，计算结果与数值模拟结果的比较表明，两者符合较好。

Abstract

Abstract:A formula of Froude number at the section of starting flare is deduced in this paper.It is shown that the relationship exists among the location of the flaring gate piers

the Froude number at the section of starting flare

the weir head

the head loss and the gate width.Collection of several local water plants’data is carried out and the Froude numbers are calculated by the formula.The result shows that these Froude numbers distributes between 1.7~2.3 and the average value is 2.042. Based on actual projects

the influence of the flaring gate piers location to the Froude number is discussed. The calculated results agree well with those of the numerical stimulations.
