| 摘 要： | 为实现超声平测法反射波起跳点的识别,采用两阶段法予以实现.通过分析声波的传播特性,应用数学分析方法排除表面波、横波的干扰,通过预估检测结构面的厚度,判断反射纵波到达的大致范围,结合波形分析,确定反射纵波的到达时间点.在此基础上,考虑到尺寸效应,在实验室模拟研究进行了验证.应用该方法可以较好的实现水泥混凝土板厚度的检测.

| Abstract: | In order to realize identification of takeoff of reflection wave,the paper adopted two-phase method to carry it out.Firstly,applying mathematical analysis method,disturbance of surface wave and transverse wave was obviated through analyzing ultrasonic propagation characteristic,then approximately scope of arrival of reflected p-wave was judged through pre-estimating the thickness of detecting structural plane,and arrival time of reflected p-wave was identified incorporating waveform analysis.On the basis of... |
