摘要
新疆河流多系山溪性多沙内陆河,其特点是河床纵坡陡,洪枯流量变化大,含沙量大,推移质泥沙占年总输沙量的20%左右。人工弯道式引水枢纽很好地解决了引水与排沙的矛盾。本文将这种枢纽的设计与改进及其在管理运行上的经验作一简要的介绍,供参考。
Xinjiang rivers belong to interior mountainous stream. Their characteristics are steep longitudinal slope, large discharge change between flood and dry season and a great quantity of bed load, which holds about 20% of total annual sediment discharge. Diversion sturcture in manpower curved reach solves better contradiction between diversion and sediment ejection. This paper introduces some experiences of design and operation management for this type of projects.
