Influence Analysis of Roadway Friction on Shock Wave Attenuation

Abstract:

Friction is the extremely important factor when considering the interaction between the shock wave and the tunnel wall. But so far, the impact of wall friction on the shock wave is mainly measured by experimental methods. This paper mainly discusses the effect of wall friction on the shock wave attenuation, without considering roughness, roughness elements, the viscosity of air, and the complex relationship between them; the numerical simulation calculation model is established with DYNA calculation software; the influence law of friction coefficient on tunnel shock wave propagation and attenuation is given based on friction coefficient between air medium and tunnel wall, so as to provide guidance to mining, reduce the impact of tunnel explosion shock wave on personnel and equipment and provide a design basis for shaft safety works.
