| Abstrait: |
Pingcheng Road Bridge is an urban space steel arch bridge with a main span 89 m. The space arch and curve deck system will be assembled in temporary false work, and the influence on deck system of false work under cables tensioning construction should be considered. The keys about the construction control of this bridge are as the following: 1) the reasonable tensioning time and forces of cables taken the influence of false work into account; 2) the accurate transverse pre-camber of deck system; 3) the appropriate removal time and sequence of false work; 4) the overall and local stability of bridge in the whole construction process. |
