钻孔灌注桩后注浆技术及应用

摘要

The paper discusses the grouting mechanism of the post-grouting technique for bored pile, analyzes the damage models of the postgrouting piles and the identification of the vertical ultimate loading capacity of the single pile, and proves the effectiveness and adoptability of the post-grouting technique according to the engineering case, so as to have the further application in future.%讨论了钻孔灌注桩后注浆技术的注浆机理,分析了注浆后桩的破坏模式及单桩竖向极限承载力的确定,通过工程案例表明后注浆技术的有效性和实用性,以便进一步推广应用。
