摘　　要：复合载体夯扩桩是近几年新兴的一种桩型,在地基处理中已经得到大量应用。通过对湖北某教学楼工程加固后复合载体夯扩桩进行试验和监测,来评价分析复合载体夯扩桩加固效果,从而对复合载体夯扩桩以下几个方面做了研究:夯扩桩加固机理、桩土一起作用特性、夯扩桩破坏模式和工程性质等方面。从而在探究中发现,通过采用复合载体夯扩桩加固后与传统桩地基处理效果对比分析表明,前者具有更高的操作性与良好的经济效益性。The ram-compaction is a new pile type emerged in recent years, has been widely applied in foundation treatment. Based on a teaching building reinforcement engineering in Hubei after the testing and monitoring of ram-compaction, to evaluate the strengthening effect of ram-compaction, so as to do research on the following several aspects：the ram compaction piles with compos-ite bearing base pile reinforcement mechanism, pile and soil interaction characteristics of tamping reamed pile together, failure mode and engineering properties etc. . Thus the author found in the inquiry, through the treatment effect contrast analysis of the ram com-paction piles with composite bearing base and reinforce the traditional pile foundation, the former has higher economic benefit of op-eration and good economic benefit.
