| 摘 要： | 为了研究圆砾持力层桩端后压浆效果,对椒江1号高架桥桩端持力层为圆砾的3根桩端后压浆钻孔灌注桩进行自平衡测试。结果表明,经过后压浆处理的桩承载力有大幅度提高,其中桩端阻力提高幅度较为明显,桩侧摩阻力亦有一定提高。

| Abstract: | In order to study the effect of post-grouting pile tip in the gravel layer, three post-grouting bored piles in the gravel layer of No. 1 Jiaojiang elevated bridge pier were tested with self-balanced method. The results show that the bearing capacity of pile has greatly improved after post grouting. The pile tip resistance has been increased obviously, and pile side friction also improved. |
