Preconsolidation pressure of desiccated soils
International Journal of Geotechnical Engineering, 2008Abstract During desiccation soils are subjected to very high shrinkage stresses, often of the order of 1000 kPa. However, studies on re-saturated desiccated soils do not always show evidence of these soils being subjected to very high stresses. This paper address this important issue and the reason can be attributed to the type of saturation, either by

Evaluation of preconsolidation stress by shear wave velocity
Smart Structures and Systems, 2011The behaviors of saturated soils such as compressibility and permeability are distinguished by preconsolidation stress. Preconsolidation stress becomes an important design parameter in geotechnical structures. The goal of this study is to introduce a new method for the evaluation of preconsolidation stress based on the shear wave velocity at small ...

Temperature Effect on Preconsolidation Pressure
Geotechnical Testing Journal, 1989Abstract A change in temperature is known to affect the deformation properties of a clay specimen. In order to study the effect quantitative y and its dependence on clay type a number of oedometer tests were carried out. Conventional incremental oedometer tests as well as constant-rate-of-strain tests were used. Test results clearly show

A Note on Determination of the Preconsolidation Pressure
Journal of Testing and Evaluation, 2018Abstract The preconsolidation pressure, σ′y, is commonly interpreted by means of empirical observations (or graphical constructions) with respect to e–logσ′ stress patterns (e = void ratio, and σ′ = effective stress) exhibited in the conventional oedometer test.

Effect of Preconsolidation of Settlements
Journal of the Soil Mechanics and Foundations Division, 1964By a theoretical investigation and by settlement analysis and observations on a large oil tank, it is shown that the ratio between the settlements along the periphery and in the center of a uniformly loaded area can vary within a wide range, depending on the degree of preconsolidation of the subsoil.

Prediction of the Preconsolidation Pressure and Recompression Index of Soils
Geotechnical Testing Journal, 1985Abstract Based on the generalized compressibility equation a procedure is given to estimate the preconsolidation pressure and the recompression index of stress and time dependent overconsolidated soils. This is based on knowledge of (1) the in-situ void ratio, (2) the liquid limit of the soil, (3) the in-situ overburden pressure, and (4)
