摘　　要：结合实际工程,针对出现的基桩承载力不足问题,分析原因及提出采用高压灌浆补强方案,并总结了施工工艺,钻芯及低应变补充检测结果表明补强效果良好,为类似工程处理提供新的思路。Integrating with actual engineering, in light of bearing shortage of the pile foundation, the article analyzes and puts forward high-pres- sure grouting compaction scheme and summarizes construction technology. The core-drilling and low stress compaction results show that the rein- forcement effect is great, which has provided new concept for similar engineering treatment.

关 键 词：冲孔桩 灌浆 补强
