The influence of stress path in the collapse swelling of soils at the laboratory

Abstract

The influence of stress-path in the collapse-swelling of soils has been thoroughly studied at the laboratory. The final volume change is path dependent in the swelling zone, but not in the collapse zone. Notwithstanding, for most of the wetting processes around foundations or in canals, a final state curve for every final suction value may be used. The equivalent oedometric moduli to be used for the use of elastic methods in these soils have been studied.
