Abstract

The problem of calculating the ultimate bearing capacity of screw pile has been studied by the limit equilibrium theory in this paper. The calculation methods of the critical screw pitch and the ultimate bearing capacity under two representative failure modes are proposed. Four key parameters affecting the ultimate bearing capacity are compared and analyzed, and the design optimization suggestions are put forward. The results illustrate that the ultimate bearing capacity of the screw pile is mainly affected by the shear strength of soil, the height of screw thread and the screw pitch. When designing the screw pile, the height of screw thread could be increased and the screw pitch reduced to some extent.

基于极限平衡理论的螺旋桩抗压承载力计算方法
本文用极限平衡理论研究了螺旋桩极限承载力的计算问题。提出了两种典型破坏模式下临界螺距和极限承载力的计算方法。对影响极限承载力的4个关键参数进行了比较分析,并提出了设计优化建议。结果表明:桩的极限承载力主要受土体抗剪强度、螺纹高度和螺距的影响;在设计螺旋桩时,可适当提高螺纹高度,减小螺距。
