浑水含沙率和泥沙粒度组成对膜孔灌入渗特性的影响
|
摘要
通过室内清水膜孔灌自由入渗试验和4种不同含沙率及4种不同泥沙粒度组成的浑水膜孔灌自由入渗试验,研究了含沙率和泥沙粒度组成对浑水膜孔灌入渗特性的影响。结果表明:综合考虑含沙率和泥沙粒度组成的联系,定义了相对黏粒含量的概念;基于相对黏粒含量建立了单位膜孔面积累积入渗量、水平湿润锋运移和垂直湿润锋运移的数学模型,经检验该数学模型具有较好的相关性;提出了浑水膜孔灌自由入渗情况下灌水均匀度分析的数学模型。研究结果为浑水膜孔灌的进一步研究奠定了基础。
Through indoor infiltration of clean water film hole irrigation and four different silt contend and four clay and sand grade of infiltration of muddy water film hole irrigation tests under the same condition,the influence of infiltration characteristics of muddy water film hole irrigation under different silt contend and clay and sand grades was studied.In the study eight different kind of muddy water were configured,four of them were different in clay and sand grades,but had the same silt content of 5%,and others were different in silt content that respectively by 2%,5%,7% and 9%.Soil dry density was 1.40 g/cm3.The effects of silt content and clay and sand grade on freedom infiltration characteristics of muddy water film hole irrigation were examined.Considering the combination of silt content and clay and sand grades,the concept of relative clay content was proved.Based on the concept above,the model involved film hole cumulative infiltration volume,horizontal wetting front movement and vertical wetting front movement was established,and we also found that the model had high precision.Further,the mathematical model of irrigation uniformity analysis under the free infiltration of muddy water film hole irrigation was put forward.The findings provide a theoretical foundation for further study of muddy water film hole irrigation,and technical support for the practical production and application of muddy water film hole irrigation.
