摘　　要：引水枢纽能否实现长期有效的水资源利用,关键在于河道泥沙问题的治理。为了探索泥沙处理方案,以甘肃省南部洮河左岸取水枢纽工程为例,建立河工物理模型,结合模型进行泥沙试验。结果显示,洪水初期排沙出库量为70kg/m 3,比入库量多60kg/m 3,表明初期排沙作业较为有效,闸门开度在2.0~2.5m均较为合适。试验结果可为引水枢纽项目的排沙和运行管理提供理论依据,有利于工程的长期有效运行。Whether the diversion project can realize long-term effective utilization of water resources depends on the treatment of sediment problems in the river channel.In order to explore the sediment treatment scheme,the study took the water intake hub project on the left bank of Taohe river in southern Gansu province as an example to establish a physical model of river engineering,combined with the model to carry out sediment test.The test results show that the initial sediment discharge volume of the flood is 70 kg/m 3,60 kg/m 3 more than the storage volume,indicating that the initial sediment discharge operation is more effective,and the gate opening is more suitable between 2.0~2.5m.The test results provide theoretical basis for the sand discharge and operation management of the water diversion project,which is conducive to the long-term and effective operation of the project.
