Abstract
The article is devoted to the problem of buckling of helical piles and deformation of the superstructure of oil and gas pipelines under the action of forces of frost heaving of soils. Analyzed the characteristics of the nonuniform buckling of the piles. Revealed and substantiated the necessity of development of methods for the assessment of uniformity of buckling of piles on the distribution of frozen soils. On the basis of this study offers the calculation formula, taking into account the helical blade of the piles, the results of the calculations, built the graphical dependence, formulates relevant conclusions.
