摘    要:以大跨径钢箱梁桥为例,分析了在静力荷载条件下各种因素对桥面铺装的影响。轻集料混凝土铺装方案影响因素较多。重点就剪力钉间距、直径、高度、铺装层厚度和模量、车载以及跨径等影响因素进行了比较分析。结果表明.钢箱梁桥面的轻集料混凝土+剪力钉铺装方案总体上完全可以达到当前设计要求。

关 键 词:轻集料混凝土  剪力钉  挠跨比

Abstract:Various influencing factors on the bridge surfacing under static loads were analyzed based on the example of long-span steel box-girder bridge. The paper focused on factors such as Shear pin spac- ing, diameter, height, surfacing thickness, modulus, vehicle loads and span, etc. Results indicate that the scheme combining lightweight aggregate concrete and Shear pin fully meets the design requirement.
Keywords:lightweight aggregate concrete  shear pin  deflection span ratio
