Preconsolidation pressure of desiccated soils

International Journal of Geotechnical Engineering, 2008
Abstract 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

Experimental study of a pseudo-preconsolidation pressure in frozen soils

Cold Regions Science and Technology, 2010
Abstract Preconsolidation pressure ( p c ) is an important parameter in soil mechanics. For conventional unfrozen soils, p c is an index of the loading history and has a close relationship with the mechanical properties of soils. For frozen soils, special structures exist due to the interaction between ice and soil grains.

soilphysics: An R package to determine soil preconsolidation pressure

Computers and Geosciences, 2015
Preconsolidation pressure is a parameter obtained from the soil compression curve and has been used as an indicator of load-bearing capacity of soil, as well as to characterize the impacts suffered by the use of machines. Despite its importance in soil physics, there is a few software or computational routines to support its determination.

Preconsolidation pressure of Champlain clays. Part II. Laboratory determination

Canadian Geotechnical Journal, 1983
A series of conventional and special consolidation tests was carried out on clay samples from 11 sites in the Champlain sea basin. The results show that, for a given clay at a given depth, there is a unique preconsolidation pressure – strain rate relationship independent of the tests carried out and that the relationships obtained in different ...

A critical reappraisal of “preconsolidation pressure” interpretations using the oedometer test

Canadian Geotechnical Journal, 2010
Over the past 70 years, a number of methods have been proposed for the interpretation of the characteristic vertical effective yield stress, or “preconsolidation pressure,” of compressible soils as defined using the standard oedometer test. The concept of the “preconsolidation pressure” has been extraordinarily useful in geotechnical engineering for ...
