不同断面形状对人工渠道糙率影响的试验研究
Study on Tests of Roughness of Artificial Canal With Different Sections
摘要
Abstract
To study the roughness of the artificial canal with different sections, the artificial canal with two different sections are applied to study the law of the roughness with variation of discharge and bottom slope at the conditions of two bottom slopes and five different dis-charges.The tests present that, in conditions of uniform flow in open canal, roughness varies with flow pattern in the artificial canal with same bottom slope and different section.When Fr<1, the roughness increases with the discharge decrease;when Fr>1, the roughness in-creases with the discharge increase.When the canal section changes, the variation law of the relationship between roughness and hydrau-lic factors is the same basically.The section shape of the canal is not the factor which impacts the roughness variation.关键词
