Description
Summary:The article is devoted to the investigation of the frozen soils bearing capacity of the lateral surface of ribbed piles. During the investigation we have revealed the problems of piles bearing capacity in the geocryological conditions of Yakutia on the basis of surveys of the technical condition of buildings and structures carried out for a few years from 2011-2018. A new method for calculating the damage to exploited buildings and structures is proposed. The ribbed piles offered by the authors in the course of laboratory studies showed higher bearing capacity compared with smooth lateral surface piles. Dependences of the change in the frozen soils bearing capacity on pitch and angle of the pile ribs are determined. A technique for calculating the frozen soils bearing capacity of the ribbed piles is proposed. The technological and strength properties of soil solutions for filling wells of ribbed boring piles have been studied.
