摘　　要：后注浆技术应用于灌注桩中,可以提高单桩竖向承载力特征值,文中结合某工程实例列出了注浆前后的单桩承载力特征值,给出了后注浆灌注桩的施工要求,为该技术应用于灌注桩提供了实际工程经验,可为同类桩基础设计和施工提供参考。In this paper,the post grouting technology is used in the cast-in-site pile and it can enhance the characteristic value of the vertical bearing capacity of a single pile.Based on a practical engineering,the article presents the characteristic value of the vertical bearing capacity of a single pile for non-post grouting and post grouting,and gives construction requirements and engineering experiences for cast-in-site pile by base post-grouting,which porvides peer references for design and construction of similar pile foundations.

关 键 词：后注浆 灌注桩 单桩竖向承载力特征值
