Abstract: Introducing the large urban complex project, high-speed rail station square, which takes the long-term planning subway station into consideration during the existing underground space construction. 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 reasonable pile foundation schemes in order to make sure deformation coordination and structure security of different structural systems. The specific design methods aiming at the connection node and decreasing incontinence of the subsequent underground construction are taken at the same time.
