| Abstract: | Based on the construction characteristics of the South Branch of the Guangzhou Huangpu Pearl River Bridge, some control techniques are proposed to resolve the control problems about the alignment of Linkage of main bridge and approach bridge. Tow control rules are proposed to adjust the slope of the end of the steel box girder. In addition, some relevant methods are proposed to solve the key problems about how to adjust the slope of the expansion joint. Additionally, these control techniques resolve the contradiction between the construction progress and the construction process. |
