针对声波透射法检测中由于声测管的倾斜引起的声速异常问题,提出利用最小二乘法线性回归声测管管间距,对测点声波波速进行修正,进而更准确地判定基桩质量。 Aiming at the problem of sound velocity anomalies caused by the tilting of the acoustic tube in the acoustic transmission method, the linear regression acoustic tube spacing based on the least squares method is proposed to correct the acoustic velocity at the measuring point so as to determine the quality of the pile more accurately.
