摘要
阐述了南水北调中线工程主要输水建筑物多年来进行的水力学试验成果,其项目有:水源工程丹江口大坝加高,引水枢纽陶岔渠首水闸扩建工程,输水总干渠的漳河渡槽等6项。研究内容包括泄水能力、消能防冲、水流形态、压力、水头局部损失等。还介绍了国内混凝土渠道的糙率调研及3条渠道糙率的原型观测成果。这些成果为设计提供了可靠的依据,并指出其中的有些问题应进一步研究。
The hydraulics test results on main conveyance structures of the Middle Line of Diversion Project from South to North China are represented. These engineerings contain six items, e.g.,the heightening of Danjiangkou dam, the extension works of Taocha Sluice,the Zhanghe Aqueduct on the main canal, etc..The study contents include discharge capacity,energy dissipation,flow pattern,pressure dustribution and local head loss, etc.. Investigation data on roughness n of concrete canals and prototype observed results in three operated canals are introduced. The results have provided a reliable basis for the design, and pointed out the problems to be further studied.
