ABSTRACT
The paper characterizes the state of the issue of designing effective structures of helical piles, testifying to the relevance of this scientific and technical problem in conditions of insufficient development of the existing norms. The technique of determining load-carrying capacity of a pile by the moment of screwing fixed during its immersion is considered. The correlation coefficient formula and the technique of determining the ultimate soil contact friction on the side surface of several types of helical piles developed as part of the advancement in solving the research problem are presented.
