摘要
混凝土U形渠道已在生产中广泛采用。为了便于U形渠道的合理设计和水力计算,本文推导出U形渠道水力最佳断面为水面过底弧圆心,即均匀流正常水深h_0等于底弧半径r。并给出了正常水深h。与临界水深hk的范围判别方法和计算公式。
Throngh investigation it is found that the Optimal hydraulic cross section of a U-shaped Canal is a Section with the normal depth equal to the radius of the Canal bottom arch. Interactive Computations of the normal and critical depth of a U-shaped Canal are presented.
