Abstract: The writer attempts to clarify and address two fundamental questions regarding the appropriate use of matric suction in unsaturated soil mechanics: Is matric suction a stress variable? and Is matric suction a stress state ...

Abstract: The air pressure in the unsaturated subsurface changes dynamically as the barometric pressure varies with time. Depending on the material properties and boundary conditions, the intensity of the correlation between the ...

Abstract: The Atterberg limits are empirical indices of the critical water contents defining mechanical states of soil-water mixtures between the semisolid state and plastic state (the plastic limit or wP), and between the plastic ...

Abstract: Thermal conductivity is a fundamental physical property governing heat transfer in soil. It depends on soil types, pore structure, temperature, and moisture content, and can vary over an order of magnitude. Some theories ...

Abstract: The amount of exchangeable cation (EC) and cation types play important roles in fundamental soil behavior such as mechanical, hydraulic, chemical transport, and soil water retention (SWR). A methodology is proposed for the ...
