Taking a multi-storey masonry residential building jacking and tilting project as the research object,the overall tilt rate of the building is 13.4％o,which has far exceeded the standard allowable value.In this paper,the original structure foundation was replaced by adding new artificially bored piles,and the problem of water seepage in the bearing layer at the pile end was solved by post-grouting technology,and then the building was tilted by using PLC hydraulic synchronous jacking control system with artificially bored piles as the jacking reaction platform.After the tilt correction,the overall tilt rate of the structure was reduced to l％o,and the construction effect was good,which is of reference for similar projects in the future.
