摘要
在遵循水流重力和阻力相似条件的基础上,南水北调中线工程滹沱河动床河工模型试验模型沙的选择与设计,通过对各种模型沙的特性分析研究及悬移质及床沙粒径的影响分析,确定了滹沱河河工模型试验用沙,经"96.8"洪水验证,水面线、水位流量关系及河床冲淤与原型基本相似,说明模型沙选择正确。
Following the flow of gravity and resistance in similar conditions,model experiment of choice and design of the model sand on Hutuohe River in the South-to-North Water Transfer Project was carried out.Through the analyses of the characteristics of sand and suspended sediment and bed sediment of particle size,we had determined the physical model test sand-Hutuohe River sand.After the ＂August,1996＂ flood validation,water lines,water discharge and channel were similar to the prototype,which showed we had chosen the right sand.
