［摘要］工程位于安哥拉羅安達(dá)新國(guó)際機(jī)場(chǎng)內(nèi)，各單體建筑均處于濕陷性砂土地基。對(duì)其中的航空公司辦公樓的地基基礎(chǔ)設(shè)計(jì)進(jìn)行了介紹，由于直接采用不經(jīng)處理的砂土作為地基，具有較高風(fēng)險(xiǎn)，但國(guó)內(nèi)還未有濕陷性砂土規(guī)范，所以本文對(duì)濕陷性砂土地基采用換填墊層法是如何處理的給出幾點(diǎn)建議。

Abstract: The project is located at the New Luanda International Airport in Angola and all individual buildings were constructed on the collapsible sand ground. The foundation design of airline office building, one individual building of the project, has been introduced specifically. Because it is risky to construct the office building on the collapsible sand ground directly and there is no domestic design codes of the relevant area, replacement cushion method has been used in the design of the office building foundation. Some suggestions in terms of the foundation design of collapsible sand ground have been also provided.

Keywords: New Luanda International Airport in Angola; collapsible sand; replacement cushion method
