深圳市机场南路大跨径钢-混凝土组合连续箱梁桥设计

Large Span Steel-concrete Composite Continuous Box Girder Bridge Design of Shenzhen Airport South Road

以深圳市机场南路宝安立交跨线桥为例,基于钢-混凝土组合连续箱梁桥的结构特点,论述了结构的选型、尺寸拟定、计算分析、钢结构制作及施工等方面的内容,分析了影响结构受力的主要因素,提出了具体的构造措施。

Taking Baoan flyover bridge of Shenzhen airport south road for example. This paper discus- ses the structure selection, size sketch, calculation and analysis, producing of steel-structure and con- struction, based on the characteristic of steel-concrete composite continuous box girder bridge. The main factor which affects the load-carrying capability of structure is analyzed and details on construc- tion measure are put forward.
