Analysis of the Effect of the Deep Excavation of a High-Rise Building on the Deformation of the Ground Surface and Diaphragm Wall

Abstract Study on the influence of deep excavation by top-down construction method deformation adjacent ground surface and diaphragm wall has been analyzed in detail for a foundation pit high-rise building at 27 Lang Ha, Hanoi. The analysis was implemented finite element method. influencing factors such as stiffness, depth, load, initial groundwater level were carefully investigated applying parametric study, taking two cases short-term long-term working conditions. simulated results show that settlement to depends significantly load level. Under condition, calculated larger value than under condition. horizontal displacement bending moment large load.
