摘要
通过室内螺旋锚的上拔模型试验,探讨了单节螺旋锚在砂土和粉土中的埋置深度和锚板直径对其上拔承载力的影响.通过受力分析提出了单节螺旋锚上拔破坏的模式及极限抗拔承载力的计算公式,按本文公式计算结果与试验实测值比较一致.
Baes on experimental studies on the anti-uplift capacity of single-screw helical anchors in sand and clayey sand, the effect of embedded depth and blade diameter on anti-uplift capacity of the anchor is discussed. A theoretical model was developed to predict the ultimate anti-uplift capacity of the single-screw anchrs, the results of which were in good agreement with experimental results.
