摘　　要：桩基可以提高地基承载力,有效控制地基与基础的沉降。钻孔灌注桩直径大、承载力高、施工方便、可以就地灌注,因此在工程项目中的应用较广。本文结合具体项目对后注浆钻孔灌注桩施工工艺的特点、作用肌理进行分析,研究后注浆灌注桩设计方法,分析其在具体项目中的应用效果。Pile foundation can improve the bearing capacity of foundation and effectively control the settlement of foundations.Bored pile is widely used in engineering projects because of its large diameter,high bearing capacity,convenient construction and on-site grouting.Combined with specific projects,this paper introduces the characteristics and function mechanism of post-grouting bored pile construction technology,studies the design method of post-grouting bored pile,and analyzes its application effect in specific projects.
