【Abstract】 Based on Nanjing Jinling Hotel expansion project,this paper introduced the construction technology of large cross-section support replacement beam adopted in three layer basement structure during construction in phases, specifically expounded the design optimization, construction and demolition technology of support replacement beam, described a series of technical measures in detail. Furthermore,the technology not only solved the safety problems of large cross-section support replacement beam,but also ensured the effective docking of horizontal support when the first and second phase basement structure is under construction. The effective docking of basement structure during construction in phases is finally completed.更多还原
