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.
