The study of deformable soils is one of the key factors in determining the tire, vehicle and/or
agricultural tool design parameters. This literature review provides a brief overview of soil …

The Paper presents a constitutive model for describing the stress-strain behaviour of
partially saturated soils. The model is formulated within the framework of hardening plasticity …

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 …

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 …

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 range of problems that geotechnical engineers must face is increasing in complexity
and scope. Often, complexity arises from the interaction between the soil and the …

Gravitational forces acting on in situ bank material act in concert with hydraulic forces at the
bank toe to determine rates of bank erosion. The interaction of these forces control …

Analytical and comprehensive, this state-of-the-art book, examines the mechanics and
engineering of unsaturated soils, as well as explaining the laboratory and field testing and …

Great efforts have been made to understand and determine the stress parameters of
unsaturated soils. However, this requires elaborate laboratory tests, which are both difficult …

In this paper, several theoretical aspects for preparation of constitutive equations of
unsaturated soils are discussed. First, possible pore water states are described. Three …
