［摘要］重慶冉家壩廣場3號塔樓主體結構屋頂高度193-0m，為B級高度的超限高層建筑，結構體系為鋼筋混凝土框架-核心筒結構體系。3號塔樓橫跨于軌道5號、6號線之上。為減少軌道對上部建筑的影響，采用了與軌道完全脫開的基礎設計。通過對軌道及建筑基礎相互關系的計算分析，可知本工程基礎結構設計安全可靠，能夠滿足結構安全及建筑功能的要求。

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
