- The research investigats the secondary consolidation
of organic silts and clays. Its fundamental causes and whether it begins
simultaneously with or sequentially after primary consolidation are not well
understood. Most of what is known about the phenomena come from one-dimensional
laboratory tests under normal gravity. By increasing the gravitational field
(on a geotechnical centrifuge) while holding the applied total stress constant,
the scaling of temporal events may be changed and the nature of this change
can give insight into the cause and time variation of the phenomena. Secondary
consolidation has an impact on volume change of soils in many aspects of
civil engineering.
