- Abstract
Structured soils exhibit significant different mechanical behaviours compared to the remoulded soils due to the influence of soil structure. Intrinsic compression line for structured soils is introduced based on the deformation behaviours. Structural factor is proposed to characterize the soil structure. Volume change equation of structured soils is established by incorporating structural factor. And the evolution law for structural factor is proposed. A constitutive model for structured soils is proposed based on the modified Cam clay model. Three new parameters are added to the proposed model compared to the original model. The proposed model is validated by the experimental data of two kinds of structured soils.
