Studies about Creep Characteristic of Silty Clay on Triaxial Drained Creep Test

Abstract:

The creep characteristic of saturated silty clay was studied by triaxial drained creep test through two stress paths of axial loading and lateral lightening. According to test data, some conclusions were submitted. First, the axial creep laws between the two stress paths were consistent on the drainage conditions. Volume strains were much smaller than axial strains. Volume strains presented shear dilatancy along with lightening confining pressure. The silty clay creep coefficient was put forward and its variation law was summarized. The silt soil creep coefficient was closely related to the deviatoric stress level. The two had a linear relationship. The silt soil creep coefficientincreased with deviatoric stress level and had no matter with the confining pressureand loading path.
