摘要
随着桥梁结构形式地不断发展,钢混组合梁作为一种新型结构,在国内已得到广泛应用.由于其结构形式具有自重轻、抗弯刚度大、截面尺寸小等特点,钢混组合梁结构形式能有效减少对桥梁基础的要求.钢混组合梁在公路建设中,能够减少钢材使用、降低工程造价、施工难度低等优点,因此其应用越发广泛.研究以沪通铁路长江大桥四线特大桥为例,介绍了一种跨河道大跨径钢混组合梁整体吊装施工技术,并阐述了其施工工艺及特点.
Abstract
With the continuous development of bridge structural forms,steel-concrete composite beams,as a new type of bridge structure,have begun to be widely used in China.Due to its lightweight,high flexural stiffness,and small cross-sectional size,the steel-concrete composite beam structure can effectively reduce the requirements for bridge foundations.The steel-concrete composite beam has the advantages of reducing the use of steel,lowering engineering costs,and having lower construction difficulties in highway construction,so its application will become increasingly widespread.This study takes the Shanghai Tong Railway Yangtze River Bridge as an example to introduce a construction technology for the overall hoisting of large-span steel-concrete composite beams across river channels,and elaborates on its construction technology and characteristics.
