The steel underpinning system and the key points of the design in the jack lifting and leaning rectification project of a six-storied dormitory building are introduced,and by setting up a model through the finite element analysis software ANSYS, the stress and strain of the underpinning system under working condition have been calculated so that the cooperation between underpinning system and brick wall is analysed.The results ancl experience from this project can be the references of other jack lifting and leaning rectification projects.
Keywords:  jack lifting; leaning rectification; underpinning; finite element analysis
