通过在实际应用现行超声波验桩规程时引用超声声速等参数，结合规程中的有关判断依据， 对桩身缺陷和质量等级可作出更合理的判断。此外，就检测中常遇到的声测管不平行问题，可采用斜 率法对测距进行修正。
Through the practical application of the current ultrasonic staking procedure, the ultrasonic sound velocity and other parameters are referenced, and based on the relevant judgment criteria in the procedure, a more reasonable judgment can be made on the pile defect and the quality grade. In addition, the detection often encountered in acoustic tube is not parallel to the problem, the slope method can be used to correct the ranging.
