微型桩在临时边坡支护中的应用

微型桩作为一种新型的支挡结构,施工快捷且经济合理,常用于边坡支挡中。该文运用结构力学和弹性地基梁理论,并以贵阳市环城路某段边坡工程为案例,讨论了不同形式的微型桩在计算时的受力方式和运用条件,得出微型桩的位移和内力。考虑桩土相互作用的原则,工程最终采用了双排钢管桩进行支挡,为边坡阻滑结构的设计提供了合理的依据,并得出一些有益的结论。

Application of Micro-pile in Temporary Slope Support

As a new support structure,micro-pile is rapidly constructed and low cost,so it is often applied in slope support.Based on the structural mechanics and elastic subgrade theory and through a case study of a slope project on the ring road in Guiyang,the stress modes and application requirements of differently-shaped micro-piles under calculation are discussed to get the displacement and internal force of micro-pile.Giving the pile-soil interaction principle,double rows of steel pipe piles are adopted to support in this project,offering reasonable basis for landslide blocking design and some beneficial conclusions.
