预应力钢—混叠合连续梁的设计与施工

The design and construction of pre-stressed steel-concrete composite continuous beam

结合工程实例,探讨了大跨钢—混叠合连续梁的设计,介绍了钢箱梁的施工,并对无伸缩预应力混凝土桥面板施工进行了分析,经检测,钢—混叠合梁结构自重轻、投资少,值得推广应用。

Combined with practical engineering, the author discusses the design of large-span steel-concrete composite continuous beam, introduces the construction of steel box girder, and analyzes the construction of non-stretch pre-stressed concrete bridge deck, and points out that steel-concrete composite beam structure has light deadweight and requires less investment, which is worthy to be popularized and applied.
