<正>观测了钢筋混凝土箱梁桥沥青混凝土铺装施工过程,介绍了沥青混凝土铺装施工的方法;通过对不同工况的计算,分析了沥青混凝土铺装施工荷载对桥梁的影响;对静力计算数值和实测数据进行比较,指出铺装过程中对桥梁产生的影响远大于静力计算的结果。提出应加强对沥青混凝土铺装过程的控制,在铺装前进行相关计算,避免因铺装施工使结构产生损伤。

The observation of the pavement construction on a concrete boxgirder bridge is introduced to determine the influence of the construction on the bridge.The comparison between the static computation values and measuring values suggests that the influence of the bridge during the construction procedure is much greater than the static state.It is necessary to reinforce the control of the pavement construction procedure and to do essential calculations in order to minimize the possibility of impairing the structure.
