| 摘 要： | 根据桩基体系中桩顶、桩身、桩端等各部位反射波的特征,分析产生离析、夹泥、缩径、断裂、扩径差异等缺陷的原因,探讨各类型缺陷的处理措施,建立同相反射波和反相反射波的判别标准。通过对大量现场检测资料的分析,验证判别标准的合理性和适用性,该方法对提高桩身完整性判别检测的精度有较大帮助。

| Abstract: | According to the characteristics of reflect waves on pile cap, pile body and pile tip, analyses are made to find causes for the defects such as segregation, sandwich silt , necking-down, fissure and expanded diameter difference, the measures are discussed to treat the above defects, and the standards are established to determine in-phase and reversed-phase reflected waves. By analyzing a large quantities of field detecting data, the rationality and applicability of the standards are verified, which will improve the precision for determining the integrity of pile body. |
