Сравнительный анализ результатов определения несущей способности забивной висячей сваи

Abstract

This article is aimed at verifying a methodology for defining the load capacity of adriven hanging pile, which is part of a foundation laid on a real construction site after conducting engineering and geological surveys. The results of an automated analysis of the pile load capacity implemented in 2 software complexes (SC) – a) "Zapros" software (version 21.1.9.7), which is a part of SCAD Office software and b) with a subsystem "Statika" – a part of the complex planning system Ing+ were compared. Further, we performed a calculation analysis according to the SP 24.13330.2012 "Pile Foundations. The updated Version of SNiP 2.02.03-85", where the load capacity of a driven hanging pile is calculated as a sum of the resistivity of the foundation ground under the low part of the pile and the ground on its side surface. A comparative analysis of the obtained results established that the value calculated in SC Statika, namely in module Statika ground –concrete piles, is lower than that obtained by manual analysis according to SP (the spread is 2.19%). At the same time, the result obtained with the Zapros software produces an error higher than the normative value by 13.55%. Thus, the study has shown inconsistency in the results obtained using normative requirements and automated analysis. It can be concluded that the use of software complexes does not guarantee an entirely reliable result, thus not abrogating the responsibility of the planner and requiring additional verification.
