Abstract: The overconsolidated clay in natural sedimentary site has both anisotropy and dilatancy properties, but there are few constitutive models that can accurately describe the above properties at the same time, and it is even more rare to apply the model to the analysis of soil cavity expansion stress field. Three points of work have been done in this paper.（1） Based on the UH model of overconsolidated clay, the phase transformation stress ratio with the overconsolidation degree is introduced, and th... More
