Abstract

This study focuses on developing new expressions correlating hydraulic conductivity (K) in binary mixed soils with intergranular porosity (neq) and overall regularity (OR). Through a series of constant head hydraulic conductivity tests on three types of coarse-grained soils, varying proportions of low plastic river silt (Sp = 0% to 40%) were mixed with sand. Initially, sand-river silt binary assemblies were prepared with an initial relative index (Id = 0.92). Analysis reveals significant influences of particle shape factors on hydraulic conductivity. The study elucidates the relevance of overall regularity (OR), shape factor (SF), and intergranular porosity (neq), introducing two novel parameters: [(OR)0.5 × SF × neq] and [(1 + EG)/(SD)5 × (neq)0.02]. The experimental findings highlight the robust predictive capability of these multi-variable expressions in systematically determining hydraulic conductivity. Such insights hold particular significance in geotechnical engineering, especially in understanding hydraulic responses within binary granular systems. Ultimately, this research contributes to a more profound comprehension of soil behavior and carries substantial practical implications for a wide array of engineering applications, facilitating more accurate predictions and design considerations in geotechnical projects.

二元颗粒系统的导水性:它取决于整体规则性和晶间孔隙率吗?
本研究的重点是开发新的表达式,将二元混合土中的导水性(K)与粒间孔隙度(neq)和整体规则性(OR)联系起来。通过对三种粗粒土进行一系列恒定水头导水试验,将不同比例的低塑性河道淤泥(Sp = 0% 至 40%)与砂混合。最初,沙子和河道淤泥的二元组合是以初始相对指数(Id = 0.92)制备的。分析表明,颗粒形状因素对水力传导性有重大影响。研究阐明了整体规则性(OR)、形状因子(SF)和晶间孔隙率(neq)的相关性,并引入了两个新参数:(OR)0.5×SF×neq]和[(1+EG)/(SD)5×(neq)0.02]。实验结果凸显了这些多变量表达式在系统确定水力传导性方面的强大预测能力。这些见解对于岩土工程,尤其是理解二元颗粒系统的水力反应具有特别重要的意义。最终,这项研究有助于更深入地理解土壤行为,并对广泛的工程应用具有重要的实际意义,有助于在岩土工程中进行更准确的预测和设计考虑。
