摘要
通过试验和理论分析,概括了挤扩支盘桩的结构组成、施工工艺、成桩机理,以及挤扩支盘桩竖向抗压和抗拔的受力性能,总结了支盘在承受竖向荷载的过程中,总侧摩阻力和总端阻力的发展规律,得出支盘发挥主要作用的结论。
According to the test and theoretic analysis,the paper surveys the structural components,the construction craft,the pile mechanism of the squeezed branch piles and its stress performance of anti-pressure and anti-pulling,sums up the development law for the general side friction and the general end friction in the process of bearing vertical loading of the branch pile,and concludes the main role of the branch pile.
