| Abstract: | As a usual method for testing concrete, it may test and destruct a prototype only once, which can not define the position, scope of drawbacks of concrete, and can not demonstrate the extent of structure damaged by the method. Nondestructive testing can abandon these shortcomings, so is valued and applied in the engineering practice. This article analyzes the ultrasonic method, one of nondestructive testing methods. It illustrates the basic natures, spreading characters of ultrasonic wave, viewing errors by this method and remedies. Finally, it stresses the importance and measure of improving the technique. |
