摘　　要：长短桩复合地基是一种新型的地基处理形式。本文依据具体的工程实例,根据工程基桩承载力差异较大,且单桩承载力严重不足问题,经多种处理技术方案比较,提出在原工程桩间补入C20素混凝土短桩,组成长短桩复合地基方案。经计算满足设计要求,补桩施工完成,经检验,复合地基承载力结果达到设计要求。The long- short- pile composite foundation is a new type of foundation treatment. Since there exited some problems such as the distinct difference of the vertical bearing capacity among foundation piles and the serious lack of the vertical bearing capacity of a single pile for a given project, a scheme of long- short- pile composite foundation that the short C20 pure concrete piles are intercalated among the primary engineering pile based on the comparative study was introduced. The bearing capacity of composite foundation after treatment is sufficient for the design requirement by the theoretical computation.
