One-Dimensional Consolidation Model Based on Sub-Superloading Surface Theory and its Applicability to Consolidation Behavior of Pleistocene Clays under Kansai International Airport

摘要

The upper Pleistocene clays under Kansai International Airport arerntypical “quasi-overconsolidated clay”, of which mechanicalrncharacteristics are quite distinctive from those of mechanicallyrnoverconsolidated clays. An elasto-viscoplastic one-dimensionalrnconsolidation model is proposed in order to express time-dependentrnconsolidation behavior for quasi-overconsolidated clays. The numericalrnsimulation of a series of long-term consolidation tests for Ma10, upperrnPleistocene clays under Kansai International Airport, is carried out inrnwhich the model proposed is applied. The applicability of proposedrnmodel is confirmed through a comparison between the experimentalrnand analytical results.
