声波透射法在混凝土灌注桩工程检测中的运用

Application of acoustic transmission method in concrete cast-in-place pile engineering inspection

通过对声波穿过混凝土灌注桩桩身各横截面的物理声学参数及波形变化的处理、分析和判断,确定桩身混凝土缺陷的位置、程度和范围,推定桩身混凝土的完整性、连续性和均匀性状况,评定桩身完整性等级。

Through the changes of physical acoustic parameters and waveform of acoustic wave passing through each cross section of concrete pouring pile, processing, analysis and judgment are carried out to determine the position, scope and degree of defects in concrete pile, infer the continuity, integrity and uniformity of concrete pile, and evaluate the integrity grade of pile.
