The behavior of an unsaturated soil tested under undrained loading conditions depends on the magnitude of the pore-air and pore-water pressure developed. This paper derives pore pressure parameters that can be utilized in determining the pore pressure response of the compacted clayey materials.
Pore pressure parameter expressions are also derived for the pore-water pressures induced as a result of isotropic stress changes and deviator stress changes during undrained loading.
The parameters required to computation in the proposed model can be readily determined from the conventional triaxial compression tests. To examine the degree to which the proposed pore pressure model reflects the results of triaxial tests, The back analyses carried out, It is shown from the examination that agreements are generally satisfactory.
