摘　　要： 基于广州珠江黄埔大桥南汊悬索桥施工特点,针对悬索桥主引桥衔接处纵坡线形控制难题,提出解决方案。对于主桥端部钢箱梁纵坡线形的控制,提出两个调坡原则;对于伸缩缝纵坡线形的控制,提出须解决的关键问题及解决方法。所提方案解决了施工进度与施工工序之间的矛盾。 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.
