Abstract:The height of the main structure of the No. 3 tower at Ranjiaba Square in Chongqing is 193-0m. It is an out-of-code high-rise building of level B. The No.3 tower structural system is a reinforced concrete frame-core tube system. The No.3 tower spans over metro line 5 and line 6. In order to reduce the influence of track on the upper building, a design approach that the foundation completely separates from the track was used. Through the calculation and analysis of the relationship between the track and the building foundation, it shows that the design of the foundation of this project is safe and reliable, and it can meet the requirements of structural safety and building functions.

Keywords:out-of-code high-rise building; equivalent sound pressure level; frame-core tube structure; foundation design
