摘要
分析了常见桩身缺陷产生的原因以及反射波波形和参数的特点,提出了基桩存在蜂窝、离析、扩径、缩径、断裂以及桩底沉渣等情况的判断依据和方法。
The cause for existing common pile defects, the wave and parameters characteristics of reflected wave all have been analyzed. Based on such analysis, some criteria and methods have been proposed for judging the situation of honeycomb, segregation, reducing, diameter extension, breaking zone and sedimentation on the bed of pile, etc.
