DETERMINATION OF THE BEARING CAPACITY OF A PILE-SCREW FOUNDATION IN A CRYOLITHOZONE

The relevance of the study lies in the problem of calculating the bearing capacity of pile-screw foundations in the conditions of cryolithozone propagation under the influence of static pulling and pressing loads. Pile-screw foundations are a fairly new type in construction, although the first menti...
