From Particle Gradation to Soil Water Retention and Suction Stress Characteristic Curves of Sands Using the Unsaturated Discrete Spheres Method

Abstract

AbstractThe soil-water retention curve (SWRC) and suction stress characteristic curve (SSCC) are fundamental to understanding the hydromechanical behavior of unsaturated soils. However, direct laboratory measurement of these curves is often challenging ...Practical ApplicationsUnderstanding soil moisture retention and stress responses is crucial for designing stable slopes, resilient foundations, and safe earthen infrastructure such as dams or levees. Traditional methods for measuring these properties are ...
