摘 要:在对抗拔试桩资料整理与分析的基础上,详细讨论了抗拔桩粘着力系数α与桩周土不排水抗剪强度Cu的关系及桩拔、压摩阻比与桩长径比的关系,以及桩周土的土性、桩的类型和施工方法等对它们的影响,并提出了预估桩抗拔承载力的方法.Based on the analysis of the uplift pile test data, the correlation of the adhesion factor versus the undrained shear strength of the soil around the uplift pile and the reduction factor of the skin friction between the uplift pile and the compression pile versus the slenderness ratio of the pile has been discussed in this paper in detail. The effects of soil behaviours and the pile type, etc. on the adhesion factor have also been studied. In addition, the prediction method of the pile's uplift capacity is presented.
