Introduction With the progress of science and technology, the continuous development of the cities, the shield construction is widely used in city subway.
The receiving probe will receive the wave reflected, and by recoding the time that the ultrasonic wave propagates in the cutters, the value of the cutters' wear can be calculated easily, the speed of the ultrasonic wave propagates in the material of the cutters can be measured by experiments[3].
