The article presents the methods for reliability analysis of CFA (Continuous flight augering) piles with under-ream on settlement criterion. The presented methods of reliability analysis take into account the limited statistical information about the controlled parameters in the design mathematical models of limit states. That increases their practical significance (fewer control soil samples are required for testing), but reduces the informativeness of the reliability analysis results. The paper also presents methods for reliability analysis of CFA piles in the presence of complete (full) statistical information for individual parameters that increase the informativeness of the reliability analysis results. The article deals with numerical examples of reliability analysis for CFA piles with under-ream at the lower end. The paper is aimed at fulfilling the requirements of Russian Federal Law No. 384-FZ and Interstate standard GOST 27751-2014 Reliability of structures and foundations for the design and inspection of pile foundation with CFA piles.
