One of the consequences of global warming is the increasing of the phenomenon of cyclical freezing / thawing of the soils. This preliminary experimental study aims to understand and quantify the variations in the behaviour of a silty soil subjected to a cycle of freezing / thawing through a series of laboratory tests. After a soil characterisation, shear and oedometric tests are performed before and after freezing on several soil specimens. The results, which are temporary and not exhaustive, are deduced from the oedometric curves and Mohr-Coulomb diagrams obtained. Some comments can be drawn from the superimposition of the oedometric curves and Mohr-Coulomb diagrams of the soil before and after freezing. All tests are carried out according to Swiss standards.
