Design of Continuous Flight Auger Pile Foundation for a Multi-Storey Apartment Building

Abstract

The object of this work was studying, systemizing and describing continuous flight auger (CFA) pile foundation design for a residential complex and calculating the bearing capacity of a single СFA pile on the basis of Russian Building Code. This thesis was written on the request of the YIT Lentek JSK Design Department.

The information for the theoretical part was gathered from Russian Building Codes, theoretical manuals, other common available materials (including the Internet), and project materials and documents kept in the archive of YIT Lentek JSC. The practical part of the study presents the calculation of bearing capacity of a single СFA pile based on Russian Building Code, called SNiP 2.02.03-85 “Pile Foundations”.

General systematization of the process of CFA pile foundation design for multi-storey apartment buildings, which is useful for further studies, was implemented on the basis of gathered and analyzed materials. Results of a single СFA pile bearing capacity calculation serves for the company as a starting point in determination of bearing capacity of a single CFA pile of a given diameter and length for further considerations and comparisons with other variants of piling.
