Review of soil-water characteristic curve equations
Practical applications of unsaturated soil mechanics still lag behind the state-of-the-art knowledge. The main stumbling block is the time-consuming processes involved in the measurement of the unsaturated soil parameters ...
Soil-water characteristic curves for compacted clays
Effect of rainfall on matric suctions in a residual soil slope
A slope stability study involving shallow slip surfaces should include the effect of negative pore-water pressures in a slope. A field instrumentation program was carried out to monitor negative pore-water pressure (i.e., ...
Consolidation apparatus for testing unsaturated soils
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 ...
Discussion of “unsaturated hydraulic conductivity of two compacted barrier soils”
Unsaturated hydraulic conductivities were measured in the laboratory and the field for two compacted fine-grained soils used as barrier layers in landfill final covers. The instantaneous profile method was used for the ...
Permeability functions for unsaturated soils
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 ...
Coupled model for heat, moisture, air flow and deformation problems in unsaturated soils
Through extensive review and study on the different aspects of coupled processes in unsaturated soil, a general three-dimensional mathematical model for coupled heat, moisture, air flow, and deformation problems in unsaturated ...
Instrumentation of an unsaturated residual soil slope
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 ...
Measurements of matric suction and volume changes during inundation of collapsible soil
Reduction in soil volume due to inundation under a constant total stress is a phenomenon referred to as collapse. Collapse is exhibited by soils during a change of state from an unsaturated to a saturated condition. Several ...
