摘要： 抗浮锚杆作为一种有效的抗浮技术手段，能解决大型建筑地下室工程的抗浮问题，但是目前抗浮锚杆的设计与施工还没有明确的规范可循。结合具体工程实例，探讨了抗浮锚杆在粘性土层中的设计与施工应用技术。同时，通过对现场抗浮试验锚杆试验研究，对抗浮锚杆在粘性土层中是否能正常工作的评判标准给出了建议，对于类似工程应用具有一定的参考价值。

Abstract: As an effective measures for balancing the buoyancy of the underground structures, the uplift anchors are widely used in the design and construction of basements for large building structures. However, no design and construction specifications available for the uplift anchors. This paper discusses the design and construction of uplifting anchors in cohesive soils from a case history. The capacity of the uplift anchor was full scale tested on site and the method of determining the ultimate uplift capacity was also suggested.
