摘要
新疆河流一般较多为山溪性多泥沙内陆河,河道短且水量较小,推移质泥沙含量高。本文以伊犁喀什河引水渠首工程为例,结合弯道水力学及各参数方法,简单介绍引水渠首弯道部分的运行特点。可以看出这种利用弯道水流产生横向环流从而起到排沙目的的布置形式在实际过程中运行良好,引水防沙效果较好,是创新的第三代弯道式渠首。
Rivers in Xinjiang mostly belong to mountainous sediment inland rivers, which are characterized by short river course, smaller water volume and high content of bed-load sediment. In the paper, water diversion canal head project of Xinjiang in Kashi River is adopted as an example, and corner hydraulics and various parameters methods are combined for the simple introduction of the operation features of water diversion canal head project corner part. It is obvious that such layout pattern of utilizing corner water flow to produce circular flow for the purpose of sand discharge is well operated in practical process. It has better water diversion and sand prevention effect. Such layout pattern is regarded as innovative third generation corner canal head.
