ABSTRACT

Pres-tressed concrete continuous rigid frame bridges are widely used in valley and river crossings, and the issues of alignment, stress and safety control during their construction are receiving increasing attention. Taking a continuous steel structure with a main span of 96m+180m+96m as an example, this paper discusses the monitoring scheme, alignment and stress measuring point arrangement; establishes a construction monitoring model and calculates the stress and deformation of all construction stages; conducts construction monitoring of the whole process. The results show that in the bridge construction process, through reasonable construction supervision to ensure that the bridge is smoothly united and the bridge structure alignment meets the design requirements, effectively controlling the construction quality of the bridge.
