摘要
本文根据 ＰＩＴ的工作原理，结合我国公路现场桩基检测的工程实践，对桩身中应力波的传播、波速和桩长的计算，测试结果的分析与处理进行了探讨。在此基础上，对ＰＩＴ反射波法进行桩身结构完整性测试的波形判读中的有关问题进行了讨论，以供桩基检测技术人员参考。
Based on the working principle of PIT and it combines with project practice for pile foundation test of Chinese highway,this paper discusses the propagation and velocity of strees wave in the pile length the count of the pile length the analysis and handling of text results. The author also discusses the relevant problems in the wave form interpretation of the pile construction integrity is tested by the back wave method of PIT. This is for the technician of pile foundation test reference.
