A permeameter for unsaturated soil

Transport in Porous Media, 1991
A 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.

Water in Unsaturated Soil

2018
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.

Consolidation Apparatus for Testing Unsaturated Soils

Geotechnical Testing Journal, 1996
Abstract 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 ...

Anisotropy of Unsaturated Soils

Soil Science Society of America Journal, 1984
Abstract 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

Instrumentation of an Unsaturated Residual Soil Slope

Geotechnical Testing Journal, 1999
Abstract 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.

Settlement rate of foundations on unsaturated soils

Canadian Geotechnical Journal, 1999
This 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 ...

Principles of physical modelling of unsaturated soils

2013
Centrifuge modelling has been widely used to simulate the performance of a variety of geotechnical works, most of them focusing on saturated clays or dry sands. On the other hand, the performance of some geotechnical works depends on the behaviour of shallow layers in the soil deposit where it is frequently unsaturated.
