摘　　要：在应用冲击反射法进行无损估计时 ,应力波波速测量是一项非常重要的工作 .文中介绍了单传感器测波速和双传感器测波速两种方法 ,并在制作的混凝土板块上进行了波速测量试验 ,详细分析了影响波速测量精度的因素 ,指出实验中应该注意的问题和提高测量精度的方法 .Measurement of wave speed is very important when impact echo method is applied to NDE of concrete structure. Two methods of wave speed measuring for concrete structure, i.e., wave speed measurings for one transducer and two transducers, are introduced. Experiments of wave speed measuring have been done to several concrete plates. Factors that will influence measuring error are discussed in detail. It points out what should be paid attention to in experiments and gives a method on how to reduce measuring error. Thickness of the plates is evaluated. The results are reasonable.
