| 中文摘要:通过钻孔灌注桩桩端桩侧高压注浆新工艺在上海地区的首次试用及试桩资料的分析比较，探讨了该新工艺方法提高单桩垂直承载力的机理，强调了长径比较大的钻孔灌注极采用极端压浆，特别是桩侧压浆，对于提高单桩垂直承载力具有明显效果。并详细介绍了该新工艺的施工方法。 |

| Abstract:Based on the first trial use of a new method for grouting at the bored pile end and sides, analysis and comparison of the trial pile information, the mechanism of increasing the single pile vertical bearing capacity by the new method is investigated. It is stressed that pressure grouting at the pile end,especially the pile sides,increases the single pile vertical bearing capacity greily. The construction method of the new method is detailed. |
