Unsaturated Soils: Experimental StudiesResearch in the field of unsaturated soil mechanics for high plastic clays is very active. One area of considerable current interest is development of general constitutive models for unsaturated clay based sealing materials in a frame work that can be implemented ...
First the unsaturated degrees of soils are described by low and high suctions, respectively. By reviewing the theory of saturated soil mechanics, the current commonly accepted theories of unsaturated soil mechanics are introduced. Then, the testing methods for measuring the water retention and ...

It has become a common practice that the hydraulic conductivity of unsaturated soils is estimated from the soil-water characteristic curve by using either empirical method or statistical method. The estimated results by the empirical method are dependent on the empirical parameters while those by the ...
ASCE / MARCH 2006 toward soil property assessment for unsaturated soils Fredlund et al. 1996 . The primary objective of this paper is to illustrate the progression from the development of theories and formulations to practical engineering protocols for a variety of unsaturated soil mechanics problems...
The bearing capacity of strip footings on unsaturated soils is studied using slip line theory. The suction profiles considered are non-uniform with depth and correspond to vertical flow of water by infiltration or evaporation. The slip line theory assumes a plastic equilibrium state of a Mohr–Coul...
Unsaturated soils are ubiquitous on the surface of the Earth and play an important role in construction engineering and vegetation growth. Their properties are governed not only by the stress state but also by the moisture content (i.e., suction), and are influenced by many factors such as en...
