Abstract (AI)
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.
Key Findings
1
A combined geotechnical and structural-health monitoring method is proposed for controlling the condition of the transport tunnel beneath the Smolenka River within the central WHSD section.
2
St. Petersburg transport infrastructure requires specialized technical-condition management throughout construction and operation because climatic and technogenic factors significantly affect structural performance.
3
The authors identify integrated structural health and geotechnical monitoring as an up-to-date diagnostic approach for transport objects in St. Petersburg.
4
The discussed monitoring examples demonstrate lifecycle-oriented condition control for diverse transport structures under challenging urban construction and operating conditions.
5
The paper presents monitoring systems applied to bridges, tunnels, embankments, mound structures, and other transport-infrastructure elements, including the Bolshoi Ilyinsky Bridge and Gorelovsky overpass.
