In order to obtain the distribution of peak reflection shock wave overpressure along rigid wall ,the finite element models were set up. The problems were solved by using AUTODYN software and analyzed by comparing with the calculation results of TM5-855-1. The prediction formula was conducted to calculate the distribution of peak reflection shock wave overpressure along rigid wall at different scaled dis-tance. The prediction formula could provide a reference in design for explosion-proof walls and structural anti-blast .
