The author of the article considers it necessary to perform a bearing capacity analysis to ensure the safety of high-rise structures in the medium of loose clayey soils. The author proposes a new mechanism of the soil failure prevention that illustrates the nature of the bearing capacity. The soil medium is considered to be discrete rather than solid. The distribution of stresses in the core sections and in the base of long vertically loaded bored cast-in-situ piles is identified on the basis of field tests. Effectiveness of several actions aimed at the increase of the point resistance of piles is the subject of the research.
