Consolidation analysis for unsaturated soils
Canadian Geotechnical Journal, 2004This 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.

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 ...

A permeameter for unsaturated soil
Transport in Porous Media, 1991A permeameter for unsaturated soil was developed by observing the way in which pore water recovers hydrostatic equilibrium. It works like an hour glass that is turned upside-down everytime the state of reference (or hydrostatic equilibrium) is reached.

Anisotropy of Unsaturated Soils
Soil Science Society of America Journal, 1984Abstract A conceptual model is applied for quantitative evaluation of the anisotropy factor during desaturation. The soil is assumed to consist of many thin parallel layers having different hydraulic properties. A uniform density distribution function is used to represent the saturated hydraulic conductivity probability of the various

Water in soil usually fills soil pores only partially, therefore soil unsaturated with water is the prevailing state of soil. The soil unsaturated with water is a necessary condition for the majority of the plants that grow in the environmental conditions of Europe.

Instrumentation of an Unsaturated Residual Soil Slope
Geotechnical Testing Journal, 1999Abstract The stability of slopes has become a major concern in areas that experience frequent periods of heavy rainfall such as the tropical areas of Southeast Asia. Previous research has indicated that rainfall has a detrimental effect on the stability of residual soil slopes.

Consolidation Apparatus for Testing Unsaturated Soils
Geotechnical Testing Journal, 1996Abstract An apparatus for performing consolidation tests under K0 conditions was designed and constructed for testing unsaturated soils. Three types of consolidation tests are of interest in unsaturated soils. These are: (1) constant water content loading tests, (2) consolidation under a net total stress, and (3) consolidation under a ...

Settlement rate of foundations on unsaturated soils
Canadian Geotechnical Journal, 1999This paper deals with the one-dimensional consolidation of unsaturated soils due to the application of external loads. A simple equation is derived that enables one to predict the rate of settlement of shallow foundations with time. This equation uses the constitutive relationships proposed by Fredlund and Morgenstern to define the volume change of ...
