混凝土的超声波探伤法是通过弹性波与混凝土介质相互作用时传播参数的变化,来查明缺陷及其产生的原因,估计混凝土的质量情况,和有依据地预测结构的工作能力。考虑到混凝土缺陷产生及发展的各种原因,我们引入缺陷形成因素这一概念,以便研究施工(不密实,搅拌不匀,分层,水泥石与骨料或钢筋的粘结力 The ultrasonic flaw detection method of concrete is to identify the defects and their causes by estimating the propagation parameters when the elastic wave interacts with the concrete medium, to estimate the quality of the concrete, and to predict the working ability of the structure in a predictable way. Taking into account the various causes of the development and development of concrete defects, we introduced the concept of defect formation factors in order to study the construction (non-compact, uneven mixing, delamination, cement stone and aggregate or reinforcement
