［摘要］廣州舊白云機(jī)場(chǎng)改造工程總建筑面積約10萬(wàn)m2。由于建筑功能改變以及增層要求，原結(jié)構(gòu)部分地基基礎(chǔ)不能滿足新的荷載要求，采用錨桿靜壓樁對(duì)原結(jié)構(gòu)地基基礎(chǔ)進(jìn)行加固。著重介紹錨桿靜壓樁在地基基礎(chǔ)加固設(shè)計(jì)中的計(jì)算方法和施工參數(shù)的確定原則,同時(shí)通過(guò)對(duì)傳統(tǒng)錨桿靜壓樁的施工工藝進(jìn)行適當(dāng)改進(jìn)，極大地提高了壓樁機(jī)的周轉(zhuǎn)速度，擴(kuò)大錨桿靜壓樁的應(yīng)用范圍。

Abstract:The total area of old Guangzhou Baiyun Airport structure-reinforcement project is almost 100 thousand square meter. Because of changing on building use and adding more floors, a number of original foundation is not able to supporting the new loads and anchor jacked pile is adopted to reinforce the original building foundation. It primarily introduces the calculating methods and construction parameters of anchor jacked pile in foundation reinforcement. Moreover, by improving the construction technology of conditional anchor jacked pile, the turnaround speed of jack machine is greatly improved and the range of using anchor jacked pile is extended.
Keywords:foundation reinforcement; anchor jacked pile; relieve loads ; harmoniously cooperate
