综合判定方法在超声波测桩中的应用

Synthetical Method for Ultrasonic in the Pile Testing

本文讨论了声波各项指标在基桩测试中的应用,分析了原有规范在基桩超声波测试评定中的不足之处,提出了解决的办法。从理论上证明了波速、波幅在评定混凝土缺陷时是相互影响的,指出了各个指标对缺陷测试的贡献,提出了利用各个指标进行基桩质量的综合判定的方法,即在基柱起声波测试时应采用综合判定以达到评定结果的可靠性。

In the paper, the parameters of ultrasonic are discussed in the pile testing, the lack of previous criterion in the determinant method of ultrasonic are pointed out. Wave velocity and wave amplitude which are testified in the determinant method of ultrasonic in the testing affect each other, meanwhile the parameters apply to the disfigurement testing of the pile, which brings forward the synthetical determinant method of the parameters in the pile testing, the reliable result can be gained.
