摘　　要：简要介绍了高应变动力试桩法的检测原理,并结合工程检测实例,总结了预应力管桩在检测过程中常遇到的桩质量问题,如桩身断裂、接桩质量差及假收锤等。根据试桩检测结果,分析和判断施工中存在的问题,提出了注意事项。The princi pie of High Strain Dynamic Testing for the pile was introduced. With a example of engineering test, summarize the ordinary quality issues in testing ofpre-stress tube-pile, such as crack on the pile, the poor quality of pile connection and fake hitting. Based on result of pile test, analysis and estimate the problems during the construction, and some cautions is put foreword.
