Author points out that the influences of three-dimensional effect on speed of stress wave must be considered when reflection method is used to measure the depth of shallow defects in pile foundation.
运用波动力学理论 ,分析了应力波在三维状态下的纵波波速与一维状态下纵波波速的区别 ,指出在用反射波法判别基桩浅部缺陷的深度时 ,应考虑三维效应对应力波波速的影响 ,所采用的波速应为正常波速的 1。

The current specification for low strain dynamic testing of piles gives an unclear definition about shallow defects in the section method of reflection wave.
现行的基桩低应变检测规程，在反射波法一节中对于浅部缺陷定义不明确，且判别方法对于非科研性生产单位来讲难以掌握和实施。
2) shallow defect
浅部缺陷

The formsoft motion of piles with shallow defects,especially serious defects,are more of vibration than waves in Low Strain Testing,the normal test criterion on the location and degree of defect is inappropriate.
浅部缺陷桩特别是浅部严重缺陷桩在低应变测试时主要表现为振动而非通常情况下所分析的波动,致使通常的评判缺陷深度及程度的准则不再适用。
