Abstract:LEEZA SOHO Building consists of 2 single anti-symmetrical towers. The load of the two towers is concentrated, and its difference from atrium load is significant. The connecting line tunnel of Metro Line 16 and Metro Line 14 runs through 3 or 4 floors of the whole basement. Considering the complex structure of the building itself and the influence of the surrounding structures, the pile-raft foundation scheme was adopted in the main building area, and the beam-slab foundation and counterweight + uplift pile anti-floating measures were adopted in the pure underground garage area. The pile type and design parameters were determined by synthesizing survey data and foundation shape and size. The design parameters of pile foundation were verified by test pile engineering, and then the calculation and analysis of the interaction effect between pile design and foundation were carried out to ensure construction quality and safety of pile foundation. The final settlement observation data of buildings verified the rationality of foundation design of this project.
Keywords:LEEZA SOHO； super high-rise building; foundation design; interaction analysis
