摘　　要：青居船闸下引航道靠船墩处天然地基承载力较低,为满足设计要求,采用高压旋喷桩加固处理。通过该工程高压旋喷桩的施工,探讨了其在地基处理中的特殊性,为今后嘉陵江流域内高压旋喷桩施工提供了宝贵的经验。At berthing dolphin of lower navigation approach channel at Qingju navigation lock,the natural foundation bearing capacity is low.To meet design requirements,high pressure rotating spouting piles are used for stability enhancement.Particularity of high pressure rotating spouting pile construction in foundation treatment is discussed in this paper,which provides valuable experiences for the similar projects in Jialingjiang River Basin.
