Accuracy in Building Bridge Superstructure Constructions via Cantilever Concreting or Assembly Method

This article examines the cantilever method for constructing bridge superstructures and highlights the lack of specific accuracy requirements in Bulgarian regulations for this technique. The study defines the necessary accuracy for building bridge superstructures using the cantilever concreting and assembly methods and calculates the precision required for determining the spatial coordinates of observed points on the bridge cantilevers. Through mathematical analysis, permissible deviations in height and plan position are established. The findings emphasize the importance of precise geodetic measurements and high-accuracy instruments to ensure structural integrity and minimize construction errors, ultimately contributing to improved quality control in cantilever bridge construction projects.
