BEARING CAPACITY OF STRIP FOOTINGS IN FROZEN SOILS

The first part of this paper discusses some basic requirements for the determination of the allowable bearing pressure for frozen soils, with a particular reference to the delayed deformations due to creep and consolidation, which occur simultaneously in frozen soils containing large amounts of unfrozen water. In the second part of the paper, it is shown how the creep settlement and failure of a strip footing in frozen soil can be predicted by using a simple mathematical model of an expanding cylindrical cavity. With the help of a previously obtained solution, valid for a circular footing, and an appropriate empirical depth factor, the present solution is then extended to cover also the bearing capacity of footings of any shape and at any depth of embedment.
