我国北方干旱地区宽浅河流上修建的引水工程,一般闸坝较低,主要为农业生产服务.各地由于严重缺水,工程的引水率均较高,而排沙用水很少,泥沙问题严重.如何设计好这类工程?如何运行管理?使此类工程充分发挥效果,是建设中常碰到的伺题.本文根据部分工程和试验资料,对上述问题进行了初步小结和探讨. Diversion projects built on wide and shallow rivers in arid areas of northern China are generally low in dam gates and serve mainly agricultural production. Due to severe water shortages, the water diversion rates of the projects are all high while the discharge of sediment water is very small and sediment problems are serious How to design such a project? How to run the management? Making the full effect of such a project is a common problem encountered in the construction.This article has carried on the preliminary summary and discussion to the above-mentioned questions according to some engineering and experimental data.
