摘　　要：对聚苯乙烯泡沫塑料作空心板内膜并设置横隔板后的空心板桥进行整体性能分析,利用有限元程序MIDAS/Civil建立装配式预应力混凝土空心板桥计算模型,探讨设置横隔板后装配式预应力混凝土空心板桥荷载横向分布。研究结果表明:采用聚苯乙烯泡沫塑料内膜作装配式空心板的内膜,会使整桥的荷载横向分布变得均匀,增大空心板桥的板间联系,加强装配式混凝土空心板桥的整体性。The overall performance of the hollow plate bridge with the polystyrene foam plastic and setting horizontal clapboard is analysed.The space finite element calculation model of hollow plate bridge was built using a finite element program Midas/Civil.The load transverse distribution of the assembly hollow plate bridge after setting horizontal clapboard was discussed.The calculation results show that the load transverse distribution of assembly hollow plate bridge becomes even when the polystyrene foam plastic is taken as intimal model,and the link between hollow plate is strengthen,so is the integrity of hollow plate bridge.
