黄河浑水特性及泥沙防渗性试验研究

黄河浑水含有大量泥沙,在流速逐渐降低的过程中,不同粒径的泥沙分选沉积,在静水环境下,能够在底部形成一层弱透水性的防渗层,在系统分析了沉积泥沙的沉积特性,粒径特征及透水性的基础上,采用室内试验模拟黄河浑水对库底防渗性能的影响,得出渗漏量与沉积层的相关关系、水头对渗流量的影响曲线,证明引黄河浑水在平原水库库底形成沉积层作为...

Study on Characteristics of Turbid Water from Yellow River and Impervious Test of Sediment

There is lots of sediment in the turbid water from the Yellow River.In the process of flow velocity reducing gradually,the different sizes of sediment would depose in sorting.In a static water environment,the sediment could form an impervious layer with weak permeability in the bottom.In the paper,through the systemic analysis of sediment deposition features and size characteristics and permeability,the correlativity between the quantity of seepage and sedimentary deposit,and the influence curve from the wa...
