摘　　要：复合载体夯扩桩是一种深基础桩型,它大幅度提高承载力的主要途径是通过加固桩端土体形成扩大头,以降低竖向应力来实现的。该技术具有单桩竖向承载力高,施工工艺简单,质量易控制,节约工程造价等特点。Composite carrier compaction pile is a kind of deep foundation pile type. The main way of improving bearing capacity ofcomposite cartier compaction pile reinforces pile tip soil to reduce the vertical stress. The technology has high vertical bearingcapacity of single pile, simple construction technology, easy to control quality, and saves the project cost.

关 键 词：复合载体夯扩桩 承载力 压缩模量 三击贯入度
