摘要:
以福建某简支梁桥为研究背景(该桥在实际工程中已被改造为半刚性整体桥),采用MIDAS/Civil软件将原简支梁桥改造为整体桥、半整体桥与延伸桥面板桥,分别建立了5座桥的全桥有限元模型,分析了它们在地震荷载下的受力差异。结果表明:简支梁桥在地震荷载作用下易引起主梁在桥台处的落梁现象,而无缝桥可有效防止该现象的发生,其中的整体桥表现出更优的抗震性能,更适用于强震区; 在地震荷载作用下,无缝桥与简支梁桥的桩基有效作用长度均在0~10D(D为桩径)埋深范围; 整体桥桩基在大震作用下的受力性能较好,可更好地保护桩基不被破坏; 延伸桥面板桥与传统简支梁桥台底桩身受力相近,其设计可参考现行有缝桥设计规范; 无缝桥与传统简支梁桥的墩底弯矩均最大,在该处易形成塑性铰; 纵桥向地震荷载作用下,简支梁桥与延伸桥面板桥的主梁受力最不利位置分别出现在跨中与墩顶处,而整体桥、半刚性整体桥与半整体桥出现在台顶处,其受力不利部位在设计中应引起重视; 该研究结果可为无缝桥的设计计算与相关规范的制定提供参考。
Abstract:
A simply supported girder bridge built in Fujian Province was taken as a research background. The bridge was transformed into a semi-rigid integral bridge in the practical engineering. On the basis, the original bridge would be transformed into an integral bridge, semi-integral bridge, and extended-deck bridge. The finite element models of five bridges were built based on the MIDAS/Civil software. The differences of their mechanical performances under the seismic load were analyzed.The results show that the simply supported girder bridge is easy to cause the girder to fall at the abutment, while the jointless bridges can effectively prevent the occurrence of the phenomenon. The integral bridge shows a better seismic performance and is more suitable for building in the high earthquake areas. The effective lengths of piles of the jointless bridges and simply supported girder bridge are at the buried depths of 0-10D(D is the pile diameter). The pile of integral bridge has a good mechanical performance under the large seismic load, which can be better for protecting the pile foundation from damage. The mechanical behaviors of the pile at the abutment bottom of the extended-deck bridge and simply supported girder bridge are similar. Therefore, the design of the extended-deck bridge can refer to the design code of the traditional seam bridge. In addition, it is also found that the bending moment at the pier bottom is the largest in both the jointless bridges and simply supported girder bridge, and the plastic hinges can be easily formed at the position. Under the action of longitudinal seismic load, the most unfavorable positions of mechanical behaviors of girders of the simply supported girder bridge and extended-deck bridge are respectively appeared at the mid-span and pier top, while those of the integral bridge, semi-rigid integral bridge and semi-integral bridge are appeared at the abutment top. More attention should be paid to these positions in the design. The research results can provide a reference for the design of jointless bridges and formulation of related codes.
