摘    要: 通过总结前人有关干支流直角交汇区水流泥沙运动研究成果,归纳了干支流直角交汇区的分区水流泥沙运动特性,初步探讨了交汇区局部水头损失计算方法,提出了新的包含水深比及回流长度的局部水头损失系数计算公式,采用长江科学院水槽试验成果对计算公式进行了验证。验证结果表明:在汇流比较小时,计算与试验成果吻合较好。

关 键 词:干支流直角交汇区  水流泥沙运动特性  局部水头损失  水槽试验

Abstract:The motion laws of flow structure and sediment transport in right-angled conjunction area of main and branch channels are complicated which makes the corresponding further researches into predicaments.Through summarizing and analyzing those previous corresponding results on the natures of flow structure and sediment transport in the conjunctions,the division characteristics of flow structure and sediment transport had been generalized.Meanwhile the calculation method of local head loss had been preliminary ...
Keywords:Right-angled Conjunction of main and branch channels  nature of flow structure and sediment transport  local head loss  flume experiment
