Abstract:The foundation and structural design of the basement for certain plot in Guangzhou Financial City were introduced. Quantitative analysis of the influential factors on the scheme of the uplift anchor was conducted to provide the basis for the optimization of anti-floating design. The stress conditions of the super-long concrete structure of the basement were analyzed in detail considering the conditions of the concrete shrinkage and temperature difference in service stage. Design work was conducted according to the results of analysis results. Skipping-floor construction scheme was used for save time, and the corresponding structural measures were taken in design and construction phase checking was conducted to make sure that the scheme was feasible and reasonable.

Keywords:basement; uplift anchor; super-long concrete structure; skipping-floor construction
