某炸药库内爆作用下坑道内隔爆防护墙厚度估算

Thickness Calculation of Tunnel Explosion Protection Wall under the Blasting Destroy in Explosive Magazine

文章以某炸药库安全评估工程的实际问题为背景,考虑到周围墙体的限制,坑道内的冲击波得以加强,以及附近坑道施工不受到影响为原则,通过数值模拟和简单公式,分析了10 t炸药库的爆炸破坏作用,提出了内爆作用下隔爆防护墙厚度的估算方法,并研究在一定的冲击波作用下隔爆防护墙的厚度,为安全评估提供参考。

In this paper, an actual project in explosive magazine safety evaluation is taken as the background. When the explosion happens in the magazine, consider the limit of the wall, the blast shock wave in the tunnel will strengthen, and it should not affect the adjacent tunnel project. Based on those above principles, the numerical simulation and the formula calculation are used to analyze the blast destruction effect, and a thickness calculation method of the explosion protection wall under the blast shock wave load is proposed. The thickness of the explosion protection wall under a certain blast shock wave is also studied, to provide references for safety evaluation.
