Relationship between Collapse and Soil-Water Retention Curve of a Sandy Soil
Volume decrease associated to an increase of water content of a soil, at almost constant total stress has been termed collapse. Some evidences from laboratory tests and field observation indicate that soil collapse can arise from moisture variation or, more appropriately, from suction variation conditions that are far from saturation or far from zero suction. This paper deals with the influence of soil-water characteristic curve of an undisturbed sandy soil on collapse deformation. The results analyzed come from suction controlled oedometer tests and soil-water retention curves. The results show some features of the gradual collapse behavior of the tested soil and its relationship with the form and parameters of soil-water retention curve and presents an empirical equation able to calculate the collapse potential development under matric suction variations using the parameters of the soil water retention curve.
