摘　　要：低应变检测作为基桩完整性检测的主要方法之一,由于低应变检测速度快,节约成本,对桩体无破坏,在如今的工程基桩检测中应用越来越普遍。但对低应变波形的判断需要一定的经验性,且不同的桩体材料对低应变波速的影响较大。本文以基桩低应变检测波形影响因素的分析,总结不同因素对低应变波形的影响,为基桩低应变检测提供相应的参考。Low strain testing is one of the main methods of pile integrity testing.Because of its fast speed,cost saving and no damage to the pile body,low strain testing is more and more widely used in today's engineering foundation pile testing.However,the judgment of low strain wave needs some experience,and different pile materials have great influence on low strain wave velocity.In this paper,the influence factors of low strain test waveform of pile are analyzed,and the influence of different factors on low strain test waveform is summarized,which provides the corresponding reference for low strain test of pile.
