倾斜螺旋锚片锚杆上拔性能的室内试验研究

Experimental Study on Uplift Behavior of Inclined Screw Anchors

螺旋锚片锚杆（简称螺旋锚）是一种利用深层土体抗力的锚固结构。笔者通过室内模型试验对螺旋锚的倾斜角度对其上拔承载力的影响及其上拔破坏机理进行了探讨。根据试验结果，结合螺旋锚上拔时的受力分析，并利用方差分析得到了一些结论。

Screw anchor is one of the anchoring structure which is supported by the reaction of the underlying Stronger soil. Laboratory model tests are carried out to investigate the effect of inclined angle of the anchor on the uplift capacity and the mechanism of uplift failure. According to test results combined with the analysis of uplift force, some conclusions are obtained by variance analysis.
