A robust andtransparent multi-expression programming (MEP) model was employed and tuned over the synthetic dataset of soil with permeability values (k), particle diameter at the commutative distribution of 10% (d10), 50% (d50), 60% (d60) and void ratios (e). Statistical criteria were used...
英文: The flowers are wilting for lack of water.中文: 这些花因缺水而渐渐枯萎。英文: A formula for calculating the coefficient of permeability of soil-rock-mixture was proposed and was verified by the experimental results, thus a concise and useful computational tool for the theoretical calculation...
Predicting the permeability function for unsaturated soils using the soil-water characteristic curve[J]. Canadian Geotechnical Journal, 1994, 31(4): 533-546. doi: 10.1139/t94-062 [6] ZHAI Q, RAHARDJO H. Estimation of permeability function from the soil-water characteristic curve[J]. ...
A simple technique is proposed in this paper for estimating the coefficient of permeability of an unsaturated soil based on physical properties of soils that include grain size analysis, degree of saturation or water content, and porosity of the soil. The proposed method requires the soil-water ch...
