Abstract:Because of the ground subsidence, a 3-storeyed masonry-concrete building became dangerous with southeast inclination. Static pressure pile underpinning was used to reinforce the foundation. After consolidation, the design, construction and test of two-direction rectification by jack-up were made, and it was proved successful. The design and construction of rectification of deviation were introduced.
