摘　　要：结合南京河西地区某基坑工程,提出了在该地区进行基坑开挖时的一些施工工艺优化方法,认为使用钢筋混凝土灌注桩做围护桩效果较好,并具体针对该基坑施工中出现的问题,提出了处理偏位桩的基本原则和具体的相关措施,很好地解决了该基坑险情问题,对该地区的其他基坑工程具有借鉴意义。Based on the retaining pile lateral displacement problems occurred in an excavation project in Hexi district of Nanjing, an optimized construction flow and remedying countmeasure are proposed. It is suggested that cast-in-place concrete pile is able to present better retaining performance than other comparable retaining structures. The basic fundamentals and detailed steps are recommended, which well solve the retaining pile displacement problems, supposed te be a well-done reference for related excavation projects.
