Abstract
Matric suction can be used as one of the principal stress state variable to define the constitutive behavior of collapsing soils. The collapse behavior of a compacted soil was studied in the laboratory using a modified conventional oedometer and a tensiometer for the measurement of matric suction. The results show that collapse is a transient, continuous process. The results were used to model the volume change of a collapsible soil during wetting. The theoretical formulations derived for the model were based on unsaturated soil mechanics principles. Results obtained from the numerical model compared well with the laboratory measurements.
