摘要
对抗拔承载力系数λ进行简要评述,通过对3个工程实例的Q-s曲线进行数学方法拟合,得出其极限抗拔承载力,同时按照规范方法计算其单桩极限抗拔承载力,然后对两者关系进行比较。对抗拔桩设计中的抗拔承载力系数λ取值及桩侧摩阻力fs的取值进行了探讨,所得结论将进一步对抗拔桩工程设计提供有益的参考依据。
The actual study of uplift capacity factor λ is reviewed. According to the load-displacement date, the limit of resistant extraction bearing capacity is forecasted by mathematical theory and the criterion method, and the results are compared. The uplift capacity factor λ and side friction fs are discussed, the conclusions are useful for the design of resistant extraction pile.
