The research on the explosion shock wave propagation and attenuation technology in tunnel engineering had been a hot issue at home and abroad. The installation of a series of wave-eliminating interceptor in tunnel engineering was beneficial to attenuate explosion shock wave in tunnel engineering. It was rapidly achieved to attenuate the explosion shock wave. In this paper, based on the clarification of the propagation law explosion shock wave in air, explosion load in tunnel engineering was analysed. And the waveform characteristics and propagation law of explosion shock wave were revealed. Then the rectification mechanism was got. The interaction between the explosion shock wave and the interceptor was analysed. Then the reflection mechanism and the disturbing mechanism were obtained. With the numerical simulation method, the propagation law of explosion shock wave under different angles of the interceptor was studied. The attenuation law of explosion shock wave was revealed. The optimal angle of interceptor was achieved.
