摘　　要：简要分析了声波检测过程中影响声时变化的因素,并介绍了在声测管间距线性变化的情况下,运用最小二乘法直线拟合校正声速值,从而对桩身混凝土质量做出正确的评价。This paper briefly analyzed the factor of influence the ultrasonic time variety in course of the ultrasonic detection,and introduced how to adopt least squares technique to fit a straight line for supersonic velocity correction when the distances of the pipes are linear change,thereby we can make out correct evaluation for the concrete quality of the pile.

关 键 词：超声波检测 曲线拟合 线性变化
