Structural Health and Geotechnical Monitoring During Transport Objects Construction and Maintenance (Saint-Petersburg Example)

A considerable part of St. Petersburg transport objects demands special approaches to their technical condition management on all lifecycle stages due to city construction and operation specifics. Among them there are negative factors (climatic and technogenic nature) that are actively influencing constructions technical condition. Up-to-date diagnostic approach is various examples of monitoring systems implemented on city transport objects: bridges, tunnels, embankments and mound constructions, as well as separate elements of transport infrastructure. In particular, Bolshoi Ilyinsky Bridge and Gorelovsky overpass. As a successful example of combination of geotechnical monitoring methods and structural health monitoring the method of technical condition control of the transport tunnel under the river Smolenka as a part of the central section of the Western High-Speed Diameter (WHSD) in St. Petersburg offered by authors is presented in this article.
