SWCC测定过程产生的容重变化对SWCC参数的影响

open access: yes, 2007
土壤水分特征曲线(SWCC)测定过程本身会引起很大的容重变化。随着容重的增大,土壤的持水特性也发生改变。为了明确这种容重变化对土壤水分特征曲线的影响,本研究以4种原状土壤为例,用离心机法测定了不同定容重下的土壤水分特征曲线,分析了容重变化对Brooks-Corey和van Genuchten模型参数的影响。结果表明:土壤的容重越大,相同吸力下所对应的有效饱和度就越大,水分特征曲线就越平缓。4种土壤的参数A和α均随容重的增大而减小,可用幂函数表示。黑垆土和土娄土的&lambda ...

A Framework for Estimating Matric Suction in Compacted Fine‐Grained Soils Based on a Machine Learning‐Assisted Conceptual Model

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 9, Page 2177-2199, 25 June 2025.
ABSTRACT In this study, a hybrid black‐ and white‐box machine learning (ML) framework is proposed for matric suction estimation in compacted fine‐grained soils, utilizing ML techniques, namely, particle swarm optimized support vector regression (PSO‐SVR) and multi‐gene genetic programming (MGGP). This objective is achieved through developing a novel ML‐

A Novel Three‐Phase Interface Premelting Theory for Determining Unfrozen Water Content in Unsaturated Soil

open access: yesWater Resources Research, Volume 61, Issue 6, June 2025.
Abstract The soil above the water table in the shallow layers of the Earth is typically unsaturated, and understanding the complicated multiphase contact modes and interactions in unsaturated is crucial for accurately simulating multi‐physical field coupling and predicting foundation deformation in frozen soil region. In this study, a theoretical model

Prediction of SWCC for unsaturated cracked soil considering development process of cracks

open access: yes, 2013
Cracks are widely presented in natural and engineered soils. Cracks provide preferential pathways for water flow and significantly increase the hydraulic conductivity of the soil mass.

Estimation of soil water characteristic curve parameters in different models in light soils [PDF]

open access: yesرویکردهای نوین در مهندسی آب و محیط زیست
In addition to soil water content, soil matric potential is also important for plant growth. Soil water characteristic curve (SWCC) or soil moisture characteristic curve describes soil water content and soil matric potential relationship.

Comparison of soil-water characteristic curve (SWCC) on unburned and burned soil at varying temperature [PDF]

open access: yes, 2016
Fires can reduce soil infiltration capacity, induce soil water repellency and increase runoff and erosion. This study examines the effect of temperature under natural and laboratory condition of soil samples collected from hillside at Jalan Gambang.
