Unsaturated soils
<p><span style="mso-ansi-language: EN-US;" lang="EN-US">Results of triaxial tests performed in saturated and unsaturated compacted soil specimens with different interstitial fluids are presented. Tests were carried out in order to study the influence of the fluid relative dielectric constant, <em>ε<sub>r</sub></em>...

In this paper, two new state variables are included in a conventional elastoplastic model, Modified Cam-clay, to incorporate the influence of pore size distribution changes in the mechanical behavior of unsaturated soils. The first state variable allows capturing the influence of large pore changes in the mechanical behavior, and is controlled by an evolution la...

The SFG model was proposed in attempt to provide a consistent description of the stress-strain behaviour of unsaturated soils, including compacted soils and soils dried from slurry. It differs from existing models mainly through two aspects: a consistent description of volume change, yield stress and shear strength behaviour of unsaturated soils and a smooth and...

This paper presents the development of an instrumented channel for two-dimensional multiphase flow of automotive fuels in unsaturated soils. Flow experiments were performed using water or diesel in an eolian sand at residual water saturation, a particular case of multiphase flow. Aspects such as the visual monitoring of the infiltration experiments and the gr...
