（中国建筑设计研究院上海分院， 上海 200120）[摘要] 无锡九龙仓二期项目采用钢筋混凝土剪力墙结构。为了提高桩基的单桩承载力、减少桩基沉降量，采用钻孔灌注桩，并在桩端与桩侧后注浆。本文对该工程的后注浆施工要点进行简要介绍，并分析了后注浆工艺的原理。[关键词] 后注浆; 钻孔灌注桩; 单桩竖向承载力特征值中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2013)S2-0650-03作者简介：金建，一级注册结构师，Email:jinj@shh.cadg.cn。Bored pile post grouting technique in the application of wuxi wharf phase ii project(China Architecture Design & Research Group (Shanghai), Shanghai 200120, China)Abstract: The concrete shear wall structure was adopted for Wuxi wharf phase it. In order to improve the bearing capacity of the pile and decrease settlement of pile foundation, pile is the bored piles, on the pile end and pile side with post grouting construction technology. The project after the grouting construction points, and analyzed the principle of grouting process was briefly introduced.Keywords: post grouting; bored pile; characteristic value of vertical bearing capacity of single pile
