TLDR
In this article, the effect of stress state on unsaturated shear strength of a Korean residual soil was studied using modified triaxial tests, and the results showed that the soil-water characteristic curve was not affected by stress state.Abstract:

Review of fundamental principles in modelling unsaturated soil behaviour
TL;DR: A review of constitutive models for unsaturated soils is presented in this paper, focusing on the fundamental principles that govern the volume change, shear strength, yield stress, water retention and hydro-mechanical coupling.

Unsaturated soil mechanics: Critical review of physical foundations
Rafael Baker,Sam Frydman +1 more
TL;DR: In this article, it is suggested that the identification of matrix potential with ( u a ǫ−ǫ u w ) results from neglecting the adsorption potential, and adopting an unrealistic pore space model.

Shear Strength Equations for Unsaturated Soil under Drying and Wetting
TL;DR: In this article, a series of unsaturated consolidated drained triaxial tests were conducted on statically compacted sand-kaolin specimens under drying and wetting to examine the validity of the proposed equations.

Soil Mechanics for Unsaturated Soils
TL;DR: In this paper, the Mecanique des sols reference record was created on 2004-09-07, modified on 2016-08-08, and it was used for the Sols non satures reference record.

Equations for the soil-water characteristic curve
Delwyn G. Fredlund,Anqing Xing +1 more
TL;DR: In this paper, a nonlinear, least squares computer program is used to determine the best-fit parameters for experimental data presented in the literature, based on the assumption that the shape of the soil-water characteristic curve is dependent upon the pore-size distribution.
A constitutive model for partially saturated soils
TL;DR: In this paper, a constitutive model for describing the stress-strain behavior of partially saturated soils is presented, formulated within the framework of hardening plasticity using two iodependent sets of stress variables: the excess of total stress over air pressure and the suction.

A Constitutive Model for Partially Saturated Soils
TL;DR: In this paper, a constitutive model for describing the stress-strain behavior of partially saturated soils is presented, formulated within the framework of hardening plasticity using two independent sets of stress variables: the excess of total stress over air pressure and the suction.
Journal ArticleDOI
The shear strength of unsaturated soils
TL;DR: In this paper, the transition from a saturated soil to an unsaturated soil is described in terms of two independent stress state variables, i.e., the shear strength of unsaturated and saturated soil.
