摘要
以流域高质量发展大背景下灌区建设发展的现实需求为出发点,简要归纳了从取水头部到渠系末端,渠灌区所存在的四个方面的工程泥沙问题,在此基础上重点回顾和总结了包括渠首工程泥沙问题、干渠粗颗粒泥沙处理技术、明渠挟沙水流运动理论及灌区泥沙治理方略发展沿革、实现渠灌区浑水安全输移与水沙调控目标的相关理论与方法等几个方面的研究进展。分析探讨灌区工程泥沙问题妥善解决需进一步开展研究工作的重点与目标,对更好解决灌区泥沙问题,保障大型灌区输配水系统长期安全可持续运行,具有重要意义。
To satisfy the actual needs of the construction and development of irrigation districts under the background of high-quality development of the river basin,this work briefly summarised four aspects of engineering sediment problems existing in the canal irrigation district,from the head of the water intake to the end of the canal system.More specifically,the research progress of these problems,including the sediment problem in the canal head engineering,the treatment of coarse-grained sediment in the main canal,the theory of sediment-laden flow in the open channel and the development of sediment control strategy in the irrigation area,and the related theories and approaches in achieving the safe transportation of muddy water and regulation of water-sediment in the canal irrigation area,are reviewed and summarised.Ultimately,this work analysed and discussed the key points and goals of future work in properly solving the sediment problem in irrigation area,which is of great significance to deal with the sediment problem and ensure the long-term safe and sustainable operation of the water delivery and distribution system in large irrigation areas.
