摘要
依托乌奎高速上跨苏州路改扩建工程的空心板桥梁为例,利用目测与仪器相结合的方式对既有桥梁进行检测,评价了桥梁总体技术状况,并采用梁格法建立空间有限元模型分析空心板梁整体受力,验算结果表明:桥梁总体技术状况为2类,空心板梁承载能力满足规范的要求。
Bridge bearing capacity analysis is an important part of road reconstruction and expansion project.Taking the hollow slab bridge as an example,it evaluates the overall technical condition of the existing bridge by combining visual inspection with instrument,and establishes a spatial finite element model with grillage method to analyze the overall stress of hollow slab beam.The results show that the overall technical condition of the bridge is two types,and the bearing capacity of hollow slab beam meets the requirements,of specification.
