摘要
通过室内膜孔单点源自由入渗和单向交汇入渗试验资料,分析了膜孔灌单点源自由入渗量和单向交汇入渗量的变化规律,研究了膜孔灌单向交汇入渗减渗量和交汇界面面积之间的关系,建立了基于减渗量和交汇界面面积的膜孔灌单向交汇入渗量数学模型。该模型具有明确的物理意义,计算精度较高,是计算膜孔灌单向交汇入渗量的有效模型。该研究为膜孔灌理论与技术要素的进一步研究奠定了科学基础。
Based on the indoor experiment of film hole single point source and single line interference infiltration, the authors analyze the rule of infiltration volume of film hole single point source and single line interference infiltration, study the relationship between the reduction volume and bilateral area and develop the infiltration model of film hole single line interference infiltration. The model with specific physical meaning and high calculation precision is proved to be efficient for calculating film hole unilateral interference infiltration. The research results laid a foundation for further research of film hole irrigation theory and technological parameters.
