摘　　要：阐述了桩端压力注浆桩的施工工艺,结合实例分析桩端压力注浆效果及后注浆桩的工作特性,指出桩端压力注浆不但提高了桩端承载力,桩侧摩阻力也得到较大提高。The technology of the base - grouting way for cast - in - place piles was expounded in this paper. The grouting effect and specialitys of base - grouting pile were analyzed through a real example. It shows that press grouting not only improved the bearing capability of pile base, but also improved the bearing capability of pile skin.

关 键 词：桩端后注浆 承载力计算 施工工艺 灌注桩
