Modeling One‐Dimensional Compression Characteristics of Soils
Publication: Journal of Geotechnical Engineering
Volume 117, Issue 1
Abstract
Existing models for one-dimensional compression of clays are reviewed. Only the recently proposed Hardin's model has potential for realistic prediction of one-dimensional compression behavior of clays over a wide stress range. A new, extended power-function model is also presented and compared with the published compression data and with the Hardin's model. Both models fit the experimental data for normally consolidated, as well as overconsolidated, samples. For normally consolidated samples, they properly account for the change of the one-dimensional compression behavior, in the low stress range, for different initial void ratios. Since each of the models has only three parameters, they present an attractive replacement for the existing models. Which of the models should be used in any practical application will depend on their relative performance. It is most likely that the choice will be based on the user's preference and not on the merit of the model itself.
