| 摘 要： | In last years, the problem of building s stability in northern areas has become aggravating. The main reasons mass deformations areas follows: 1) mistakes during research, planning, construction and operation of objects; 2) negative changes in frozen ground, bound with reduction of footing s bearing capacity under technogenic impact; 3) premature wear of material of underground constructions under influence of natural and technogenic factors.
