REVIEW OF WETTING-INDUCED COLLAPSE IN COMPACTED SOIL

This paper presents the state of knowledge regarding collapse in comapcted soils. The results of a survey of the literature on the subject is presented, as well as personal experience and recent research. Case histories of collapse in compacted soils found in the literature and personal experience are reviewed and analyzed in light of the information provided. The conclusions derived from these facts are summarized. It is noted that wetting induced collapse has occurred in many types of compacted fill, including earth dams, highway embankments, and filled canyons leading to great economic and human loss. Both oedometer and triaxial laboratory experiments have been used to evaluate the collapse potential of compacted soils, and the double-oedometer technique has been found to be a relaible predictor of collapse potential for some soils but not for chemically stabilized soils.
