摘要

马蹄形过水断面因几何图形复杂,水力计算困难,为此,通过数学推导,给出了标准Ⅰ、Ⅱ型马蹄形过水断面水力要素计算公式和正常水深迭代公式,并提出判别水深范围的分界流量,便于生产实际中应用。 

Abstract

It is difficult for hydraulic calculation of horseshoe cross section in open can al flow because of its complex cross section.The formulas of hydraulic elements and iterative normal depths for standard I and Ⅱ type horseshoe cross section are deduced,and the demarcation discharge for distinguishing depth range in the cross section is presented in this paper.It can be applied to practi ce work.
