Article Preview

Based on the example of the No.4 Nanjing Yangtze River Bridge, the construction technics of precasting segmental girders by short-line is introduced. And the way of plant deformation monitoring as well as the establishment of horizontal and vertical construction control network in the precast plant are expatiated on. In addition, the measurement techniques during the installation of the fixed-mold, unfixed-mold, lineshape control techniques of the segmental girders, as well as the error correction theories during precasting process are discussed in particular. The short-line is successfully applied to the No.4 Nanjing Yangtze River Bridge, which shows its practical value in precasting segmental concrete bridges.
