【摘要】 无缝桥的引板除了要防止桥头跳车外,还需将主梁纵桥向变形传递到台后填土或接线道路中。因此,引板成为无缝桥的最易损坏的构件之一。福州大学在既有引板形式的基础上提出了一种新型Z形引板。本文以某座无缝桥Z形引板为研究对象,开展了Z形引板与不同台后填土材料相互作用对路面平整度影响的有限元计算分析。得到了不同台后填土材料对带Z形引板无缝桥路面平整度的影响因素,为日后无缝桥Z形引板台后填土材料的选取提供依据和参考。更多还原

【Abstract】 In addition to preventing jumps at the bridge head, the approach slab of the jointless bridge should be able to transfer the longitudinal deformation of the girder to backfill or roads. Therefore, the approach slab becomes one of the most vulnerable components of the jointless bridge. Z shaped approach slab is proposed by Fuzhou University based on the existing types of approach slab. One jointless bridge with Z shaped approach slab was chosen as case study. The finite element model of Z shaped approach slab and different types of backfill was established to obtain the influence of the Z shaped approach slab-backfill interaction on the pavement roughness. This research could provide the basis and reference for the selection of the backfill for jointless bridge with Z shaped approach slab in the future.更多还原
