| Abstract: | Triaxial creep test for specimen of frozen clay has been carried out. The technical creep theory of frozen clay and its rheologic constitutive equations have been proposed to analyze stress and displacement of frozen wall. Finally, the calculating formulas of thickness of frozen wall and radial displacement have been derived. |

| Keywords: | frozen clay hardening theory ageing theory triaxial creep long term strength |
