金沟河二级水电站引水渠首设计与排沙措施研究

Study on the Design and Sand Drainage Measures of Drainage Canal of Jingouhe Second Cascade Hydropower Station

金沟河为多泥沙河流,径流主要靠冰川、永久性积雪的消融和夏季降水补给,河道水量小,河床多为砂砾石阶地,厚度可达数十米。该文介绍金沟河二级水电站引水渠首设计及泥沙处理措施,可为类似工程设计提供借鉴。

The Jingou River is a multi-sediment river.The runoff mainly depends on glaciers,permanent snow loss,and summer rainfall recharge.The river channel has a small amount of water,and the riverbed is mostly sand and gravel terraces with a thickness of up to several tens of meters.This paper introduces the first design and sediment treatment measures of diversion channel of the second class of the Jingou River hydropower station,which can provide reference experience for similar engineering design.
