Earth's surface is composed of a staggering diversity of particulate–fluid mixtures: dry to wet,
dilute to dense, colloidal to granular and attractive to repulsive particles. This material variety …

ISTVS embarked on a project in 2016 that aims at updating the current ISTVS standards
related to nomenclature, definitions, and measurement techniques for modelling …

We propose that the recently conceptualized suction stress characteristic curve represents
the effective stress for the shear strength behavior of unsaturated soil. Mechanically, suction …

La résistance au cisaillement d'un sol non saturé est écrite en fonction de deux variables
d'état de contrainte indépendantes. Une forme de l'équation de résistance au cisaillement …

Experimental studies on unsaturated soils are generally costly, time-consuming, and difficult
to conduct. Shear strength data from the research literature suggests that there is a …

Unsaturated soil mechanics has rapidly become a part of geotechnical engineering practice
as a result of solutions that have emerged to a number of key problems (or challenges). The …

Soil shear strength parameters play a remarkable role in designing geotechnical structures
such as retaining wall and dam. This study puts an effort to propose two accurate and …

The concept of the suction stress characteristic curve (SSCC) for unsaturated soil is
presented. Particle-scale equilibrium analyses are employed to distinguish three types of …

Ù à c9 á (Û¿ ua) tan ˆ9 á (ua¿ uw) tan ˆb(1) where Û is the total stress, ua is the pore air
pressure, uw is the pore water pressure, c9 is the effective cohesion, ˆ9 is the effective angle …

The measurement of soil parameters, such as the permeability and shear strength functions,
used to describe unsaturate soil behaviour can be expensive, difficult, and often impractical …
