城市立交桥梁纠偏改造工程监测分析

On supervision analysis of rectification reconstruction project for urban overpasses

针对某立交桥梁出现的侧偏病害,制定并优选桥梁顶升纠偏方案,并对匝道顶升纠偏过程进行了实时监测,确保了桥梁在顶升施工中的安全,为顶升技术在纠偏改造工程中应用和推广提供一定的工程依据。

Aiming at the bias diseases on some overpass, the paper makes and optimizes the bridge＇ s lifting rectification scheme, undertakes the real time supervision on the ramp lifting rectification process, and ensures the safety of the lifting construction, so as to provide the engineering reference for the lifting technique＇ s application in rectification reconstruction and its extension.
