Abstract: Based on the application of bridge slope adjustment and jacking construction technology in the actual construction process, the error of slope adjustment and jacking is controlled through dynamic detection.?The construction data of bridge slope adjustment and jacking of ground overpass bridge involved in the construction of bid 1 of Jiyang Road (Lupu Bridge ~ Minhang District boundary) rapid reconstruction project are adopted in detail, and the effect of controlling the construction error of slope adjustment and jacking is achieved through relevant limit setting and construction monitoring, so as to complete the synchronous jacking process of the bridge.
