Numerical Analysis on Protective Effectiveness of Composite Blast Walls against Blast Wave

Abstract:

For the comparative analysis of composite blast walls on the protective effects of blast wave, Overpressure protective effectiveness coefficient was put forward to analyze protective effectiveness and . It was studied that Protective effectiveness of composite blast walls under blast waves using 3D numerical simulation method and analysis of the amount of drugs, explosive distance, height and other structural parameters on protective effect of composite structures. The influence of several factors on forecasting formula was analyzed, such as scaled blast distance and scaled height of wall. Via fitting the simulation results overpressure formula of the back of composite blast walls was obtained. The result indicate that protective effectiveness of composite structure increases when walls height increases or scaled blast distance decreases.
