摘要
广州旧白云机场改造工程总建筑面积约10万m2。由于建筑功能改变以及增层要求,原结构部分地基基础不能满足新的荷载要求,采用锚杆静压桩对原结构地基基础进行加固。着重介绍锚杆静压桩在地基基础加固设计中的计算方法和施工参数的确定原则,同时通过对传统锚杆静压桩的施工工艺进行适当改进,极大地提高了压桩机的周转速度,扩大锚杆静压桩的应用范围。
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.
