摘　　要：抗浮锚杆施工方便快捷、经济安全,越来越多地运用于解决地下工程抗浮问题。文章针对珠三角某一医院地下室建造实际,对抗浮锚杆的力学性能进行了试验研究。通过锚杆的破坏性实验,得到了锚杆在中风化岩层中的剪应力分布规律,并给出了一种锚杆抗拔力的确定方法,为实际工程设计提供依据,为类似工程提供可靠的参考。Anti-floating anchors are applied to solve the anti-floating problem of underground construction with in- creasing attention, because of its advantages in convenience, economy and security .This paper is focus on the ex- perimental analysis of the mechanical properties of anti-floating anchors based on the practical underground con- struction of a hospital in the Pearl River delta region. The shear stress distribution of the anchors in moderately de- cayed rocks is obtained by destructive experiments and the method to determine the pull-out force of anti-floating anchors is also proposed to provide basis for peer reference of the engineering design in similar projects.
