Abstract: Based on the theory of comprehensive structure potential, the stress-strain relations
of intact loess, remolded loess and saturated loess have been researched by independent
developed true triaxial apparatus. It has been reflected that the relationship between stress ratio
structure parameter and generalized shear strain along with consolidation pressure and stress
path. The mathematical model has been established. Meanwhile, the reliability of true triaxial
apparatus and stress ratio structure parameter has been validated. It is shown that the
stress-strain relations have distinct difference for different soil states. The stress-strain relations
tend to the characteristic of strain softening or hyperbola for the intact loess. The stress-strain
relations tend to the characteristic of hyperbola and strain hardening for the remolded or
saturated loess. The soil structure reduces gradually with the increasing of shear deformation and
water content. The consolidation pressure σc and intermediate principal stress patameter b are
the influential factors for soil structure. The simulation formula can accurately reflect the theory
and experimentation. It is convenient for application in projects.
