Reliability of pile foundations in the Arctic zone of the Russian Federation (Tomsk)

Abstract

One of the main problems associated with the operation of building structures in permafrost conditions, is the deformation of support systems due to changes in soil geometric parameters. The methods used today for assessing the health of buildings and support systems are not universal. One of the important indicators during the buildings operation, which allows us to determine the health of the permafrost soil–pile foundation–structure system, is the vibrational amplitude of the supporting structure.Purpose: The aim of this work is to conduct a comprehensive analysis of the pile foundation reliability in the Arctic zone of the Russian Federation.Methodology/approach: Modern monitoring and remote sensing technologies are used to collect the real-time data. Numerical modeling was carried out to assess long-term trends in changes in meteorological parameters and their impact on pile foundations. New methods and technologies are developed to improve the stability of pile structures in permafrost conditions and permanently frozen soil.Practical implications: The obtained results can be used in design and operation of buildings in permafrost conditions. Moreover, these results can be used to develop new technologies and equipment for improving the performance in the oil and gas and other industries relating to engineering structures in the Arctic zone of Russia.
