【摘要】：总结了已有的水库及河道输沙计算方面的研究成果,认为流量、入库含沙量和库区水面比降是影响三盛公水利枢纽出库输沙率的主要因素,其中比降可以用坝前水位变幅来反映。利用2000年以后的进、出库水沙资料,建立了三盛公水利枢纽洪水期出库输沙率的计算公式,并进行了验证计算,结果表明计算值与实测值比较接近,能够满足三盛公水利枢纽洪水期的排沙计算要求。
[Abstract]:The research results of sediment transport in reservoirs and rivers are summarized. It is considered that the discharge, sediment content and water surface ratio drop are the main factors affecting the sediment transport rate of Sanshenggong hydraulic project. The specific drop can be reflected by the variation of the water level in front of the dam. Based on the data of water and sediment coming into and out of reservoir after 2000, the calculation formula of sediment transport rate during flood period of Sanshenggong water conservancy project is established, and the verification calculation is carried out. The results show that the calculated value is close to the measured value. It can meet the requirement of sediment discharge calculation in flood period of Sanshenggong water conservancy project.
