Mechanical Testing in Unsaturated Soils

Geotechnical and Geological Engineering, 2008
The state-of-the-art report presented herein is aimed at documenting, to the largest extent possible, some of the recent advances in laboratory testing of unsaturated soils for stress–strain–strength–stiffness characterization under suction-controlled isotropic, axisymmetric, and true triaxial stress states.

Permeability Functions for Unsaturated Soils

Journal of Geotechnical and Geoenvironmental Engineering, 1997
This paper examines the three categories of permeability functions for unsaturated soils, including empirical, macroscopic, and statistical models. The theoretical backgrounds and performance of each category are examined against various experimental data.

Ozonation of pentachlorophenol in unsaturated soils

Journal of Contaminant Hydrology, 2008
A heterogeneous model was developed to describe interactions between ozone and hydrophobic organic compounds, exemplified by pentachlorophenol, in highly gas-saturated vadose zones where water moisture was limited to a thin film on soil particle surfaces. The soil was assumed to be free of soil organic matter.

Thermodynamics of saturated and unsaturated soils

2020
An understanding of the behaviour of saturated/unsaturated soils is important for the design and analysis of geostructures. In this paper a continuum approach based on a structured thermodynamic theory of mixtures developed by Svendsen & Hutter (1995), in which the constituent volume densities play the role of internal variables, is applied to the ...

Airflow dispersion in unsaturated soil

Journal of Contaminant Hydrology, 2006
Dispersion data is abundant for water flow in the saturated zone but is lacking for airflow in unsaturated soil. However, for remediation processes such as soil vapour extraction, characterization of airflow dispersion is necessary for improved modelling and prediction capabilities. Accordingly, gas-phase tracer experiments were conducted in five soils

On-line estimation of biodegradation in an unsaturated soil

Bioprocess and Biosystems Engineering, 2003
The objective of this study was to develop a model-based estimator of biodegradation in unsaturated soil. This would allow real-time assessment of the efficiency of treatment bioprocesses, such as bioventilation and biopile, and eventually permit optimization through the implementation of control strategies.

Numerical simulation of unsaturated soil behaviour

International Journal of Computer Applications in Technology, 2009
The mechanical behaviour of unsaturated soils is one of the challenging topics in the field of geotechnical engineering. The use of finite element techniques is considered to be a promising method to solve settlement and heave problems, which are associated with unsaturated soil. Nevertheless, the success of the numerical analysis is strongly dependent

Consolidation analysis for unsaturated soils

Canadian Geotechnical Journal, 2004
This paper deals with the multidimensional consolidation of unsaturated soils when both the air phase and water phase are continuous. Following the approach proposed by D.G. Fredlund and his coworkers, the differential equations governing the coupled and uncoupled consolidation are first derived and then solved numerically.

Unsaturated Soil Mechanics

Environmental and Engineering Geoscience, 2007
Classical soil mechanics, as presented in 1948 by Karl Terzaghi and Ralph B. Peck in their seminal text Soil Mechanics in Engineering Practice, encompasses three broad categories of soil behavior: hydraulics (flow), plastic equilibrium (stress) and settlement (volume change).Author: In first sentence of review, please consider providing a reference ...
