Abstract: Based on the existent status of pore water pressure,by using the effective stress principle of unsaturated soil,the extension of elasticplastsion of elastoplastio model of saturated soil to unsaturated soil is carried out;a modified Cam model which can account for unsaturated soil's gradually collapsibility is established.The model has few parameters and cam get them from water characteristic curve and saturated soil's test; it is applicable in practice.

Key words: unsaturated soil, effective stress, suction, capillary stres, gravity water stress
