Design And Deformation Control On Foundation Pit Support Of TESCO Leduhui Shopping Mail In Huludao, Liaoning Province

With the rapid economic development and the gradually accelerating urbanization, theper capita space is cut down and the shortage of land resource becomes increasinglyprominent. These lead to urbanization to high attitude and underground becoming aninevitable trend. The constant emerge of high-rise buildings and deep foundation pit placegreater demands on foundation pit support. The foundation pit support is complicated andsystematic comprehensive engineering.This article first briefly analyzing the characteristics an development of the deepfoundtation pit chiefly,and expound the recent characterization and application conditionsof foundation pit support, and analyze the selection principles and methods of foundationpit support. Secondly, combined with specific engineering practice, we introduce theprevious data collection of foundation pit, the selection of supporting scheme, the design ofsupporting structure, precipitation scheme and the distribution of deformation observation.We also conduct the simulation stability analysis of supporting structure using software fordeep foundation pit support named Lizheng, put forward the reasonable suggestions forengineering construction, and then guide the later engineering such as design, construction,observation and protection of foundation pit support. Lastly, for the future trend of thedevelopment of foundation pit supporting technology proposed own some views.
