Deformation properties of frozen soils

This paper gives a brief account of the results of a series of oedometer tests and triaxial creep tests on frozen soils.

The oedometer tests are performed on artificially frozen sand, silt and clay. The tests also include ice as a reference material. The results are given by parameters describing the tangent deformation modulus and the time resistance against creep.

The triaxial creep tests are carried out on the artificially frozen clay, and on a permafrost clay from Spitsbergen. The data are interpreted in accordance with Hult's theory. The artificially frozen clay shows much higher creep resistance than the permafrost clay.

In addition to deformation moduli and creep parameters the routine data of the materials tested are also included.
