| 摘 要： | 从仪器测试参数、桩头敲击、成桩工艺等三方面，采取非常措施可获得较清晰的基桩反射波形图及桩底反射和缺陷反射，从而准确地判定桩身质量复杂缺陷的类型。强调应力波速大小与混凝土强度等级为非对应线性关系，为检测者指出了避免判定混凝土强度等级的误区。

| Abstract: | Three aspects of testing parameter of instrument, knocking on the stake-end and make-stake technology, were introduced. Distinct echo-wave charts of stake, stake-end and flaw were obtained so as to accurately determine the types of complex flaws of stake-body quality. Non-corresponding relationship of stress velocity and concrete strength was stressed. This may help inspector avoid mistakes to determine concrete strength. |
