Then uninstall soil cause the underground garage floating due to antifloating not enough. The finite element method is adopted for overloading and uninstall loading conditions, and compare the results with the abservation in the scene, they matched well.Keywords: floating of underground garage; overload; uninstallload; finite element analysis
