摘    要：随着地下空间的不断开发和利用，地下室上浮的事故时有发生，如何解决地下结构的抗浮成为突出问题．笔者通过详细比较中欧规范关于地下水浮力的荷载分类、抗浮设计水位的确定、水浮力的计算、荷载分项系数的取值及抗浮稳定性验算等内容，指出了我国规范还需要进一步完善的地方．

Abstract: With the continuous exploration and utilization of underground space, the uplift of basement occurs frequently. How to solve anti-floating of underground structure has become a very critical problem. By comparing European and Chinese standards on load classification of groundwater buoyancy, determination of anti-floating water level, calculation of water buoyancy, values of load partial factors, and calculation of floating resistance etc.,we suggest that the anti-floating design standards in China need to be improved.
