摘要
重点分析了变截面桩的一个特例:支盘桩的抗拔性能及其高抗拔力的实质。推导了不同盘间距情况下的支盘桩抗拔承载力的计算公式,并结合工程实例,指出了支盘桩的抗拔承载力主要取决于支盘阻力,为支盘桩的抗拔设计提供了必要的理论依据。
The antipulling behavior and the formula of antipulling capacity of squeezed branch pile are analysised in this paper. It is pointed out that with engineering consideration, the antipulling capacity is dependent on branch resistance. The presented study results are provided as theoretical basis for antipulling design of squeezed branch pile.
