摘要：

Based on triaxial creep tests of frozen sandy soil, it is found that the volume strain is not zero and is affected obviously by the shear stress strength during creep process of frozen sail. The shear strain is not only controlled by the shear stress strength, but also related closely to the average normal stress. It is not reasonable and feasible to calculate directly the creep parameters under triaxial stress from the uniaxial creep equation according to the traditional method.
