Confined and unconfined compression tests on frozen sands

The design of foundations in permafrost, excavation of frozen ground, and artificial freezing of ground to provide temporary support during construction of tunnels and other underground structures require understanding of the mechanical properties of frozen soils. This paper describes the equipment...
