（中國建筑設(shè)計研究院上海分院， 上海 200120）[摘要] 無錫九龍倉二期項目采用鋼筋混凝土剪力墻結(jié)構(gòu)。為了提高樁基的單樁承載力、減少樁基沉降量，采用鉆孔灌注樁，并在樁端與樁側(cè)后注漿。本文對該工程的后注漿施工要點進行簡要介紹，并分析了后注漿工藝的原理。[關(guān)鍵詞] 后注漿; 鉆孔灌注樁; 單樁豎向承載力特征值中圖分類號：TU318 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2013)S2-0650-03作者簡介：金建，一級注冊結(jié)構(gòu)師，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
