【摘要】 一栋高200m,44层的办公楼,桩筏基础,筏厚3.5m,埋深18.5m,地下连续墙高34m。基于桩基施工质量差,桩基必须进行科学加固。从现场加固桩的试验和数值分析等研究,表明大楼是安全的。本工程属于超高层建筑的深埋的补偿桩筏基础,可补偿约28%的建筑物重量,建筑沉降约为5cm,具有足够的安全储备。更多还原

【Abstract】 The 200m-high, 44-story office building is supported by a piled raft foundation with a 3.5m-thick raft buried 18m deep, enclosed by a 34m-high underground diaphragm wall. Due to the poor construction quality of the initial piles,the foundation underwent scientific reinforcement. Field pile tests and numerical simulations have verified that the reinforced foundation ensures the overall safety of the building. As a deeply embedded compensated piled raft foundation for a super-tall building, the foundation system compensates for approximately 28% of the total building weight, with a measured settlement of about 5cm, demonstrating a sufficient safety margin.更多还原
