The City

Construction of Fozhao intercity bridge in Guangzhou was a three-span prestressed concrete continuous beam bridge. The bridge adopted triangle hanging basket cantilever pouring construction method. The bridge mixed cable-stayed spans, H form tower and typical highway bridge elements. It spaned across the exiting transport hubs center, with modern and ethereal shape, and became a new landmark of the city.

During the construction of a bridge, the construction procedures may change from the originally designed procedures due to some reasons like the weather. In this paper, the influence of construction procedures on the liner and stress is investigated for a prestressed continuous beam bridge with three spans. Finite element analysis indicated that construction procedures have great impact on the liner control and they affect the middle span and side span differently. Although different sets of construction procedures cause different stress at corresponding construction stages after the cantilever construction is finished, they have no significant influence on the stress of the finally built bridge. Test data agreed with finite element analysis. It is thus the influence of construction procedures on bridge liner control should not be neglected.
