Abstract

Blast wave trap is one of the ways to deal with and reduce the effects of BLAST WAVE inside the secure underground structures. In this paper, the effect of BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP on reducing the OVERPRESSURE in the main route of the TUNNEL has been studied. Accordingly, the BLAST WAVE propagation of different explosives in various distances from the TUNNEL entrance including BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP has been simulated. Autodyn software was employed for numerical simulation.Based on the ratio of the OVERPRESSURE applied to BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP to obtained OVERPRESSURE of the main route after BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP, the appropriate distance and optimum length of the BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP were calculated. The results show that BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP can significantly reduce the OVERPRESSURE applied to the BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP zone. Besides, higher values of OVERPRESSURE before BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP zone leads to an increase of optimum length of BLAST WAVE TRAP/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> BLAST WAVE TRAP along with more pressure reduction.
