| 摘 要： | 为提高水泥土桩的抗拔和抗折能力,主要考虑不同土体和接触面摩擦系数两种因素对加劲桩抗拔性能的影响,通过三维非线性有限元单桩模型,对加劲高压旋喷桩单桩5种方案桩体的抗拔性能进行分析,结果表明：铜管在加劲水泥土桩内承受主要荷载,加劲高压旋喷桩可以满足桩体抗拔和抗折的工程要求,该分析结果对旋喷桩及类似条件下加劲桩的设计和施工具有一定的参考价值。

| Abstract: | Directed at improving the withdrawal resistant and anti-booklet ability of the soil-cement pile,this paper provides an analysis of the withdrawal resistant mechanical property of stiffening high-pressure grouting single pile in 5 different cases,based on the 3-D nonlinear finite single pile model and considering the effect on the contact surface by two main factors: different kinds of soils and friction coefficients.The results indicate that the steel pipe bears the primary load in the stiffening soil-cemen... |
