摘要
分析研究了斜面和曲面上急流的特性;建立了离心压力、重力及阻力影响下边墙一带处的水深及佛汝德数的计算式。该式可用于偏折角较小的任意边墙形状及任意底部曲面的边墙附近水深的计算。以计算实例讨论了不同反弧半径的水流扩散效果,说明反弧曲面有助于水流的扩散。
he characteristics of infinite simal cross wave on slant and curved surface are analysed. Considering field gravity,friction and centrifugal force,the formulas for predicting the Froude number and water depth along the wall are derived.The formulas proposed in this paper are applicable to the infinitesimal cross wave on slant and curved surface.
