Comparative Optimization and Application of Rectification Schemes for Shear Wall Structure

For the lift correction design of the shear wall structure, there are two schemes to choose the new underpinning structure jacking and the direct jacking under the wall. Combined with a practical project, this paper puts forward the way of opening jacking joint mainly, supplemented by underpinning structure jacking, and points out that the new underpinning structure jacking method should be designed and checked according to the space truss theory. Direct jacking with holes under the wall should meet the requirements of jacking bearing capacity, local bearing capacity and axial pressure ratio. Through the comparative analysis of the two schemes, it is considered that the opening direct jacking method should be given priority, so as to provide reference for similar projects.
