摘要: 鉴于抗拔力系数λ_i经验取值跨度大,基于λ_i计算的抗拔力具有很强的经验性,通过与抗拔试验结果的对比,说明了单桩抗拔试验是确定单桩极限抗拔力最直观、最准确的方法。试验结果分析表明,抗拔力的影响因素不仅仅是桩侧摩阻力,还受桩身材料性质控制。

Abstract: Owing to the consult value of anti-pulls out coefficient λ_i can be set in a large variety, and calculating of the pulling capacity according to the λ_i has the very strong experience. Comparisons of the result of experiments for vertical pull-out show that pile pulling test is the most direct and the most accurate method. Experiment results indicate, the influence factor of the pulling capacity is not only a side bearing capacity, but also can be controlled by properties of pile's material.
