The paper presents the method of determining the impact of an external explosion on construction barriers, taking into account the angle of the shock wave.

For the assumed parameters of the barrier and the blast load, the values of overpressure were determined, taking into account the angle of incidence and the angle of reflection. Additionally, a comparative analysis of the proposed method with other methods available in the literature was made. The convergence of the results did not exceed 10%. The proposed method allows to determine the boundary between the Mach and the incident waves.
