摘要
现浇钢筋混凝土拱桥钢桁拱架的设计及应用,主要包括钢桁拱架的设计、受力分析、加工制作、安装、预压、拆除等内容。以某大桥作为工程实例,对钢桁拱架的设计及应用方法进行详细的介绍。实践表明,钢桁拱架在钢筋混凝土拱桥主跨拱圈的现浇施工中取得了良好的效果。
The design and application of steel arch trestle of a concrete arch bridge include arch design,bearing analysis,manufacturing,installation,preforming and breakout,etc.The methods of design and application are introduced in detail as a practical project of a bridge.The result shows that the effect of steel arch trestle is better in construction of the main span on the concrete arch bridge.
