Concept and During Secondary Compression
Publication: Journal of Geotechnical Engineering
Volume 113, Issue 3
Abstract
The concept, which completely defines secondary compression behavior of any one soil in terms of a constant and the EOP e‐log is a powerful practical tool for settlement analysis and interpretation of data from load‐controlled and deformation‐controlled consolidation tests. The correct procedure for evaluating for any soil is described. The concept was used to obtain an expression for the behavior of the coefficient of earth pressure at rest, during secondary compression. This approach predicts an increase in during secondary compression. This approach also predicts that the condition will not be reached during the typical geologic age of soft clay deposits. Laboratory measurements on the behavior of including during secondary compression, are presented for four soft clays. The proposed approach also provides an estimate of in situ in soft clay deposits. Two alternative laboratory procedures were used to determine in situ for four soft clays. These values compare well with the predictions.
