摘　　要：结合已实施的具体工程,在保持既有上部钢梁的情况下,在对结构进行计算分析的基础上,对人行天桥主桥下部结构墩位进行改造。此种改造方法可大量缩短施工时间、节省造价,可为类似桥梁加固、改造起到一定的指导意义。Combined with the implemented projects, under the condition of keeping the existing upper steel girder and on the basis of calculating and analyzing the structure, the pier position of the substructure for the main bridge of pedestrian overpass is reconstructed. This kind of reconstruction method can greatly shorten the construction time, save the construction cost and provide certain guiding significance for the reinforcement and reconstruction of the similar bridges.
