（武漢冶金科技大學 430070）[提要] 通過室內(nèi)螺旋錨的上拔模型試驗，探討了單節(jié)螺旋錨在砂土和粉土中的埋置深度和錨板直徑對其上拔承載力的影響。通過受力分析提出了單節(jié)螺旋錨上拔破壞的模式及極限抗拔承載力的計算公式，按本文公式計算結(jié)果與試驗實測值比較一致。
[關(guān)鍵詞] 螺旋錨 埋置深度 錨板直徑 上拔荷載 上拔位移 臨界深度 極限抗拔承載力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.
Keywords: single-screw anchor; blade diameter; critical embedded depth; ultimate anti uplift capacity
