Abstract:The domestic and abroad design of the diaphragm walls were introduced. The analysis method and the process of two-dimensional & three-dimensional excavation of a round-shaped deep foundation pit in Shanghai were presented. The stress, lateral deformation of the support walls and stability of soil were noted. Then comparison was made among two-dimensional results, three-dimensional results and the results of site investigation. At last, mechanical model and calculation methods of deformation and reinforcement of round-shaped diaphragm walls were proposed to offer reference to the common engineering application.
Keywords:soft ground region; deep foundation pit; circular retaining structure; two-dimensional analysis; three-dimensional analysis; construction simulation; site investigation
