大跨径钢波纹管涵在高速公路的应用

On application of large-span steel bellow culvert in expressways

阐述了钢波纹管涵的优点,对其力学计算模型及设计荷载进行了分析,指出钢波纹管涵具有受力条件好、跨径大、效益费用好等优点,在高速公路高填方段以及跨等级道路时采用钢波纹管涵替代拱涵和桥梁具有广阔前景。

The paper illustrates the advantages of the steel bellow culvert,analyzes the dynamic calculation model and the design loading,points out the advantages of the steel bellow culvert,including the sound stressed condition,the large span and better benefit,and illustrates the adoption steel bellow culvert to replace the arch culvert and bridge has wider perspective for the highly filled road of the expressway and the crossing grade roads.
