多泥沙环境下渠首站排沙设计及其优化

Design and Optimization of Sediment Discharge of Canal Head Station in the Environment of Rich Sediment

由于天然地质条件及发源环境的影响,部分河流存在多泥沙显现,这对于水利工程的建设及水资源的综合利用提出了新的挑战,使得对于排沙设计的要求相对较高。金沟河流域便是如此,为进一步达到资源高效利用,在金沟河流域灌渠建设中首站采用了多级排沙的设计思路来予以实现。因此,文章针对其设计方式及其基于综合利用的优化模式加以介绍,希望能够为类似水文条件的灌渠设计、改造、建设提供必要参考。

Due to the influence of natural geological conditions and the environment of sources,some rivers carry a lot of sediment,which poses new challenges for the construction of water conservancy projects and the comprehensive utilization of water resources. It makes the requirements for the design of sand removal relatively high. This is the case with Jingou River Basin. In order to further achieve high-efficiency utilization of resources,the head station in the construction of Jingou River Basin irrigation canal adopts the design idea of multi-level sand removal. Therefore,the article introduces its design method and optimization model based on comprehensive utilization,hoping to provide necessary reference for design,transformation and construction of irrigation canals with similar hydrological conditions.
