title = "Application of a relationship between Ca and OCR* in 1-D compression analysis for clays",
abstract = " This paper presents a relation between the secondary compression index Ca and the quasi-over-consolidation ratio OCR * from the one-dimensional oedometer test results to describe the nonlinear creep behavior for overconsolidated and quasi-overconsolidated clays. The 1-D compression model based on this relationship is developed and incorporated into a FDM (Finite Difference Method) program. In this model, the lower creep rate for overconsolidated soil is explained by the decrease of secondary compression index Ca , and the viscous compression is divided into viscoelastic and viscoplastic parts, which is different from the {"}equivalent time line{"} concept. The numerical predictions show that this method can account for the nonlinear creep behavior induced by overconsolidation or quasi-overconsolidation of clays.",
