砖隔墙前爆炸泄漏空气冲击波工程算法

为了评估砖隔墙毁伤后冲击波的破坏效应,依据砖隔墙前爆炸造成砖隔墙破坏后泄漏的冲击波效应试验研究结果,结合量纲分析建立泄漏冲击波效应具体工程算法,包括泄漏冲击波超压峰值、与无砖隔墙相比的药量等效系数及有无砖隔墙的冲击波超压折减系数等工程算法。结果表明:砖隔墙的合理设置可以消耗炸药的大部分能量,体现了一定的抗爆防护作用。

Explosion-leakage Air Shock Wave Engineering Algorithm in front of Brick Partition Wall

In order to evaluate the damage effect of shock wave after the brick partition wall was damaged, based on experimental results of the shock wave effect after the failure of the brick partition wall caused by the explosion in front of brick partition wall and combining with dimensional analysis, specific engineering algorithms of the leakage shock wave effect were presented, including: the leakage shock wave overpressure peak, the equivalent coefficient of charges compared without brick partition wall and the reduction coefficient of shock wave overpressure with the presence and absence of the brick partition wall, etc. The results showthat the reasonable setting of the brick partition wall can consume most of the energy of the explosion and reflect a certain anti-blast protection.
