The Deformation Properties of Warm Permafrost Available to Purchase

Six pressuremeter tests and one multistage triaxial creep test were conducted on a prepared frozen sand at −2.5 and −3°C, respectively. The pressuremeter study suggested that the model of incompressible power-law fluid, which is sometimes used in the numerical modelling of frozen-ground geotechnical problems, would not provide a suitable “simplified constitutive relation” on which we could base the design of a new standard pressurementer test for discerning long-term creep properties of warm permafrost. The multistage triaxial creep test showed a correlation between the decreasing or increasing in volume of the specimen and the attenuating or nonattenuating character of its axial creep behavior.
