FEATURES OF THE FORMATION OF THE SPATIAL TOPOLOGY OF THE FIBER-OPTIC SYSTEM OF MONITORING PILE FOUNDATIONS IN THE CONDITIONS OF THE FAR NORTH
(pp. 42-51)

Abstract. The article substantiates the relevance of the widespread introduction of fiber-optic systems for monitoring the stress-strain state of engineering structures operated in the Far North. The results of experimental researches illustrating the technological aspects of the implementation of a monitoring system on a pile foundation of an industrial building are presented. A design based on a steel hexagon with installed fiber-optic sensors (FOS) of deformation and temperature based on fiber Bragg gratings (FBG) was chosen as a measuring device (MD) installed on a monitoring object (OM). The results of the development of the spatial topology, the switching scheme and the implementation of the proposed technical solution on the pile foundation of the OM, operated in the Norilsk industrial region, are shown.

Keywords: non-destructive testing, reinforced concrete structure, fiber optic sensor, fiber Bragg grating, fiber optic monitoring system, measuring device, monitoring, pile foundation, Far North.
