摘　　要：湖北某广场地下室上浮引起一罕见工程质量事故———地下室底板最大上浮量280mm,地下室结构的柱、梁、底板与顶板均严重开裂。通过检测及有限元模拟分析指出地下室覆土没有完成、地下水上升导致地下室抗浮不足是引起该工程事故的主要原因。根据不同的破环程度研究采用相应的加固处理方法,实施效果良好。它为处理类似抗浮不足引起的工程事故提供了较好的解决办法与全新的处理思路,具有较大的工程应用价值。A rare engineering quality accident caused by the basement floating of a square building happened in Hubei,China.The basement floor was rised by 280mm.The columns,beams,bottom and roof plates of the basement structure were seriously cracked.Through testing,limited element simulation and analysis,it was pointed out that the main reason for the engineering accident was the insufficient anti floating capacity of the basement caused by the rise of groundwater when the basement soil covering was not finished.Corresponding strengthening methods were adopted based on different degrees of damages,and the implementation effect is good.It provides a good solution and a brand-new approach for handling similar accidents,and has great engineering value.
