摘要
大直径灌注桩的检测比预制桩复杂,因此常采用超声波透射法对其检测。介绍了超声波透射法检测大直径灌注桩桩身质量、完整性的基本原理和检测方法,详细讨论了桩身缺陷性质、位置和大小的诊断方法,并用钻芯法验证数据的准确性。
The testing of large-diameter east-in-place pile is more complex than that of precast piles, so the ultrasonic transmission method is usually used to test the large-diameter cast-in-place piles. The basic principle and method of the ultrasonic transmission testing for the quality and integrality of the large-diameter cast-in-place piles are introduced, and how to judge the defect kind, position and size in pile body is discussed in all details. The results are verified by the core drilling method.
