摘　　要：复合载体夯扩桩独特的成桩原理使得桩土阻力发挥与常规混凝土桩有所区别,造成了该桩型的高应变法试验在信号采集、数据分析等方面难度的提升。从夯扩桩成桩承载原理、信号采集分析及工程实例应用3个方面研究了高应变法的适用性,在定量分析与评价夯扩桩施工质量方面进行了积极探索。The unique pile-forming principle of ram-compaction piles with composite carrier makes the pile-soil resistance play different from that of conventional concrete pile,which makes the high strain dynamic testing test of this pile type more difficult in signal acquisition and data analysis. The applicability of high strain dynamic testing is studied from three aspects：bearing principle,signal acquisition analysis and engineering application,and the construction quality of ram-compaction piles is analyzed and evaluated quantitatively.
