摘　　要：抗浮是地下室设计中重要的一环,设计时除了要考虑结构安全性之外,还应兼顾设计方案的经济性。本文结合实际工程,在地下水位较低的情况下,针对上部采用大跨度空腹夹层板结构的建筑提出了增大独立柱基自重的整体抗浮方案。从安全、经济性以及施工工艺三个方面,将该方案与底板压重、抗浮锚杆方案进行对比分析,分析表明:增加独立柱基自重为最优方案。建议在地下水位较低的情况下,采用增大独立柱基自重的抗浮方案。Anti-floating has been considered as an important step of the basement design. The economical effi- ciency should be concerned as essential as the safety of structure. Combined with engineering practice, this paper presented increasing weight of the independent base as anti-floating method for superstructure of large span Sand- wich. The optimal program ,which is increasing weight of the independent base, was discovered from aspects of safety, economical efficiency and construction technology after comparing the structural distortion and program cost with floor pressure and anti-floating anchor if it is not a high groundwater level.
