Centrifugal Consolidation Testing of Soils for Classification Purposes

摘要

An investigation on the potential for using a laboratory-scale centrifuge forself-weight consolidation of soils is described. Self-weight loading induced by the centrifuge provides a means to establish the soils' virgin compression curves for states ranging from as-sedimented to one ton per square foot effective overburden. While the effects of consolidation time on test results were investigated, time-consolidation properties were not obtained. The principal goal of the investigation was the technique's potential as a classification device based on the well-known correlation between compression properties, undrained shear strength, and Atterberg limits. The technique also shows promise for obtaining compression properties for dredged materials.
