摘　　要：结合某出现上浮问题的工程,首先通过现场观测和抗浮验算初步判断结构破坏类型,然后借助SAP2000模拟地下车库上浮的全过程,再将计算结果与地下车库实际上浮情况进行对比分析,得出了各构件的内力和位移,提出了局部整体上浮时结构位形变化的规律,给出了上浮时各构件破坏的典型特征.Taking into consideration the project in which a floating accident occurred,this paper preliminarily judged the structure＇s failure type by means of the data of site observation and anti-floating calculation,simulated the whole destruction process of the underground garage by the structural analysis program-SAP2000,compared the results of the calculation with the actual floating form,then obtained the force and displacement of the components and in conclusion proposed the law of the relationship between the underground garage＇s displacement and the distance to the building and the typical characteristics of the components in the failure state of the local-integral floating.
