低应变反射波法在基桩完整性检测中的应用

桩基的质量具有高度的隐蔽性，低应变反射波法作为基桩完整性无损检测方法之一，具有数据采集快速、方便，结果分析简单及费用较低等优点，被检测单位所采纳。简要介绍低应变反射波法的原理、桩身缺陷位置的确定、桩身完整性的判定以及一些典型波形的分析。

Application of Low Strain Reflected Wave Method in Integrity Testing of Foundation Pile

As the quality of the pile foundation is very secluded, one of the nondestructive integrity testing methods for pile foundation, the low strain reflected wave method, with such advantages as fast and convenient data collection, simple results analysis and low-cost, is adopted by testing organizations. This paper introduces the low strain reflected wave principle, the identification of location of the pile deficiencies, the determination of integrity of the pile and some typical waveform analyses.
