独塔斜拉桥拉索安装施工工艺的应用研究

斜拉索作为斜拉桥的承重构件,斜拉桥梁体施工完成后,主塔采用竖转施工,再进行斜拉索的安装施工,这使得桥梁斜拉索挂设成为全桥的施工难点。以金汇港大桥为王程背景,分析斜拉索施工难点,针对难点的处理对策及施工技术要点,对独塔斜拉桥拉索安装施工工艺进行了应用研究。

Study on Application of Cable Installation and Construction Technology of Single-pylon Cable-stayed Bridge

The stayed cable is the bearing member of cable-stayed bridge.After the beam construction of cable-stayed bridge is completed,the main pylon is constructed by vertical rotation,and then the stayed cable is installed and constructed,which makes the hanging of stayed cable become the construction difficulty of the whole bridge.Taking Jinhhui Port Bridge as the engineering background,this paper analyzes the construction difficulties of stayed cable.Aiming at the treatment countermeasures and the construction technical essentials for the difficulties,this paper studies the application of cable installation and construction technologies of single-pylon cable-stayed bridge.
