Four sounding parameters of acoustic speed, acoustic time, acoustic amplitude and basic frequency are the foundation of judging integrity of foundation pile.In the actual test of pile, each parameter is not precise enough to judge the pile quality.We must judge through comprehensive comparison.Certain abnormal parameter can not be used to make judgement; otherwise, contrary conclusions are easily obtained.And parameter of PSD and acoustic speed can be classified as same parameter.%声速、声时、声幅、主频这四个声测参数是判断桩基完整性的主要依据.而在实际桩检中,各参数都不能达到足够的精度评判出桩身质量的好坏,必须经过综合比较加以确定,仅评某一参数的异常来作出判定容易得出相左的结论.并且PSD、声速参数可以归为同一参数.
