管桩用作锚桩在静载荷试验中的应用研究

Application Research on Using Pipe Pile as Anchor Pile in Static Load Test

单桩静载荷试验中,锚桩法相比于压重平台法等其他方法具有安装简单安全,场地条件要求低、工期短等优势。通过将工程管桩用作静载荷试验中抗拔锚桩的成功实例,对管桩作为抗拔锚桩的制作方法,抗拔力、桩身强度、以及后期作为抗压管桩的工作性能进行了分析评价,以期为同类工程试验提供经验参数。

In the static load test of single pile,the anchor pile method has such the advantages as easy and safe installation,low requirement on site conditions and short construction period compared with weighted deck method and other methods.Through using pipe pile as the uplift pile in the static load test,its making method,uplift resistance,pile strength and working performance as anti-compression pipe pile at later stage are analyzed and evaluated here in detail,which could provide experiences and parameters for similar projects and tests.
