In this project, measures such as structure transformation is adopted to implement structural integration in ground complex and subway engineering with different structural system, alternative computing researches are proceeded during the selection of structural integration’s pile foundation and foundation settlement coupling and the most reasonable pile foundation schemes chosen to make sure deformation coordination and structure security of different structural systems. The specific design measure aiming at the connection node of the subsequent underground engineering is taken at the same time, which facilitates connection design and construction of subsequent engineering. The research conclusion of this paper may provide references for similar engineering construction.Keywords: underground space; integration of design; settlement coordination; coupling control
