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.
Journal ArticleDOI
Stress state variables for unsaturated soils
TL;DR: In this article, a stress state variable for an unsaturated soil is proposed on the basis of writing force equilibrium equations for each phase, within the context of multiphase continuum mechanics.
Journal ArticleDOI
Constitutive relations for volume change in unsaturated soils
TL;DR: In this article, volume change constitutive relations for unsaturated soils are proposed from a semi-empirical standpoint, where one equation describes the deformation of the soil structure and a second equation defines...

Landslides: Seeing the ground
TL;DR: In this article, the authors present the view that one of the most exciting developments is the growing potential for application of Geo- graphical Information Systems (GIS) and that making GIS goetechnically smart is a transformative development.
Journal ArticleDOI
A Large Diameter Triaxial Apparatus to Measure Pore Pressure and Displacements on a Pre-existing Shear Zone/Plane
TL;DR: In this paper, the pore pressure was measured on the shear plane and the base of specimens of Athabasca clay, Highvale mudstone, and Fort McMurray highly weathered limestone at a shear displacement rate equal or less than approximately 18 mm/day.
