This paper analyzed the influence of the ultrasonic head wave amplitude's change to the concretes sonic time value,and studied the relationship between the ultrasonic wave instrumentation head wave amplitude's change and the predicted value of concretes intensity.The result showed that the false positives of measured sonic time value caused by the ultrasonic head wave amplitude's difference,had led to large error in concretes intensity measure.In order to reduce the mistake of sonic time value,it must stipulate head wave scope read sound when calculating concrete's intensity.
