摘　　要：某高层住宅建筑的地下室受城市内涝的影响,出现底板上浮事故,导致顶板、承重柱、柱板节点产生不同程度的受损,主要的破坏形式为错位、混凝土开裂、混凝土剥落。文中从理论层面验算了原设计方案的抗浮安全系数,在此基础上制定出地下室的整体抗浮方案,对板柱节点,柱身、顶板分别制定了加固措施,具体措施包括局部置换、水泥砂浆抹面、压力注浆、粘贴碳纤维布以及挖包型钢。The basement of a high-rise residential building is affected by urban waterlogging,and the floor floats up,leading to different de-grees of damage to the roof,load-bearing column and column-plate joints.The main forms of damage are dislocation,concrete cracking and concrete spalling.The research process checks the floating safety factor of the original design scheme from the theoretical level,and on this ba-sis,formulates the overall anti-floating scheme of the basement.The reinforcement measures are formulated for the plate-column joints,col-umn body and roof respectively.
