摘要
公路桥梁为调节由于车辆荷载、环境特征及建筑材料的物理性能所引起的上部结构之间的位移,同时保持上部构造间的平顺联结,需设置伸缩装置,并通过桥梁伸缩量计算对应选择伸缩装置的类型及型号。文章针对公路桥梁设计中常用的异型钢单缝式伸缩装置和模数式伸缩装置的伸缩量进行分析计算,导出常规桥梁不同联长情况下的伸缩量计算值,便于设计人员在使用过程中参考。
The expansion devices of highway and bridge are set for adjusting the displacement between the upper structure which caused by vehicle loads,environment characteristics and physical properties of building materials and keeping the connection of upper structures smooth.The selection of type and model of expansion device is through the calculation of bridge expansion amount.According to calculating and analyzing the expansion amounts of special-shaped steel single-seam type and module expansion equipment which are used commonly in the design of highway and bridge,this paper deduces calculated value of expansion amount of conventional bridge with different long units,so that it can be referenced by designers.
