摘要

高爆炸性金属外壳弹药爆炸产生的初级碎片对相关人员和公众的安全构成重大风险。当无法保证足够的安全距离时,通常使用路障或其他保护结构来阻挡碎片,并降低引爆弹药造成的伤亡风险。本研究旨在通过概率风险评估方法,为设置路障提供决策支持,从而合理减轻大口径弹药爆炸造成的主要碎片危险。这种方法能够随机表征碎片喷射、堆叠效应、碎片轨迹、人类脆弱性和通过路障减少碎片危害。在一项案例研究中,对单个和一托盘155毫米炮弹的伤亡风险和路障的有效性进行了评估。研究发现,高度超过弹药高度的路障可以显著降低路障外的危险碎片密度和伤亡风险。当路障高度超过弹药高度时,增加路障高度的好处变得微不足道。

Mitigating casualty risks from primary fragmentation hazards
Primary fragmentation from detonation of high-explosive metal-cased munitions imposes significant risks to the safety of related personnel and the public. Barricades or other protective structures are commonly used to stop fragments and reduce casualty risks caused by detonated munitions when a sufficient safety distance cannot be guaranteed. This study aims to provide decision support for the positioning of barricades that can reasonably mitigate primary fragmentation hazards from the detonation of large calibre munitions using a probabilistic risk assessment approach. This approach enables a stochastic characterization of fragment ejections, stacking effects, fragment trajectories, human vulnerability and fragment hazard reduction by barricade. In a case study, the assessments of casualty risks and effectiveness of barricades were conducted for a single and a pallet of 155 mm projectiles. It was found that barricades with heights exceeding the height of munitions can significantly reduce the hazardous fragment densities and casualty risks beyond the barricade. The benefit of increasing the barricade height becomes marginal when it exceeds the height of munitions.
