摘　　要：根据低应变反射波法基本理论,结合实际检测经验,探讨了长细比较小的粗短桩检测的可行性和检测结果的合理性;探讨了与波长取值相关的桩长误差情况;探讨了入射波脉冲宽度对实测波形图信号及检测结果的影响;以及分析了实际检测中对可测桩长的估算方法。According to the theory of the low strain reflection wave method and combined with practical experience in testing, the feasibility of testing and the rationality of the results of the thick stubby pile which ratio of pile length and pile diameter is very small are discussed. The error of pile length associated with the value of the wavelength is discussed. The influence on testing wave signal measured in-situ and testing results by the pulse width of the incident wave is discussed. The estimation method of measurable pile length is discussed.
