内容摘要:
Since the hydraulic/mechanical behaviour of unsaturated soil is more complicated than that of saturated soil, one of the most important issues in modelling unsaturated soil is to properly couple the stress-strain relation of unsaturated soil with its water retention characteristics. A series of water retention, oedometer and triaxial tests on unsaturated Masado, a completely decomposed granite soil widely distributed in western Japan, were conducted. A special loading pattern named as constant degree of saturation, were designed and conducted for the oedometer and triaxial tests. Based on the tests results, a saturated/unsaturated soil constitutive model coupling with a deformation-dependent water retention model was proposed. After verification, the newly proposed model was applied to the stability problems of unsaturated slopes and unsaturated landslide dams.
