［摘要］地下室抗浮設(shè)計是結(jié)構(gòu)設(shè)計的重要內(nèi)容。傳統(tǒng)抗浮設(shè)計以“抗”為指導(dǎo)思想，通過設(shè)置抗浮錨桿、抗浮樁、配重等提供抗浮需要的抵抗力。但水文地質(zhì)情況復(fù)雜，目前以抗浮水位作為唯一輸入條件的被動式抗浮設(shè)計，在某些條件下，既可能導(dǎo)致設(shè)計偏于保守，又可能對偶發(fā)情況預(yù)判不足。在對一些已建項目地下室上浮進(jìn)行處理時，主動式抗浮方法比傳統(tǒng)被動式抗浮方法具有顯著的工期、成本優(yōu)勢，結(jié)合某地下室工程實例，對主、被動抗浮方法進(jìn)行綜合比較，供工程設(shè)計人員參考。

Abstract: Anti-floating design is important in basement structural design. Traditional idea is ‘resisting’, using anti-floating anchor rod, anti-floating pile and anti-floating counterweight are typical methods in design. But hydrology geology is complex, and by introducing anti-floating water level as the only input, passive anti-floating design method will cause too conservative or too radical. When dealing with some floated basement of building inuse, adopting active anti-floating method has remarkable advantages in time and cost comparing with passive anti-floating method. Active and passive anti-floating method are compared with example of some practical project for reference of engineers.
Keywords: basement； anti-floating design; active anti-floating method； passive anti-floating method
