Preparation and implementation of construction and technical survey of prestressed bridge structure
Kubová, Klaudie ; Sedláček, Ondřej (referee) ; Anton, Ondřej (advisor)
The bachelor's thesis deals with the technical survey of the load-bearing structure of the left part of prestressed motorway bridge D2-058..2. The bridge is located on the border between the Czechia and Slovakia, and it was built in 1980. The work is focused on locating the prestressing reinforcement of prefabricated beams and determining its condition. The theoretical part describes the principle of static action of reinforced and prestressed concrete, categorization of technical surveys of structures and diagnostic methods. The work also presents specific diagnostic methods for determining the position and condition of prestressing reinforcement. In the practical part, the work deals with the analysis of beams by means of ground penetrating radar and probes for analysis of the condition of reinforcement. The outcome of the work is a study of the deviations of the position of prestressing cables from the original project documentation and determination of their condition in terms of corrosion degree and grouting.
