摘要

在陆战中,战壕是重要的防御工事,为士兵作战提供保护。然而,尽管战壕具有保护功能,士兵们还是经常在战壕内受伤。缺乏相应的爆炸数据以及经验性伤害报告是一个重大的知识空白,特别是关于附近爆炸后战壕空间内传播的爆炸压力。这种缺失阻碍了爆炸参数、战壕几何形状和所报告的受伤案例之间的相关性,限制了我们对战壕内爆炸相关风险的了解。本文探讨了战壕系统内爆炸传播的关键问题,这对于评估这些结构内人员的潜在爆炸伤害风险至关重要。通过先进的计算流体动力学(CFD)模拟,该研究全面调查了军事战壕附近爆炸造成的爆炸伤害风险。研究采用了一个复杂的计算模型,分析了战壕内的动态爆炸效应,同时考虑了几何参数以及受爆炸物重量和缩放距离影响的爆炸特征。数值模拟就这些参数对爆炸伤害风险的影响提出了宝贵的见解,尤其侧重于战壕内的耳膜破裂、肺部伤害和脑外伤水平。研究结果阐明了高风险区域的独特模式,突出了由于海沟沿线的封闭和排气动力学而产生的内部爆炸的独特特征。这项研究强调了详细数值建模在评估爆炸伤害风险方面的重要意义,并为了解与军事战壕附近爆炸物爆炸相关的风险提供了新的知识基础。所获得的见解有助于加强在战壕结构附近暴露于爆炸事件的军事和民用环境中的安全措施。

Blast injury risks to humans within a military trench
In land warfare, trenches serve as vital defensive fortifications, offering protection to soldiers while engaging in combat. However, despite their protective function, soldiers often sustain injuries within these trenches. The lack of corresponding blast data alongside empirical injury reports presents a significant knowledge gap, particularly concerning the blast pressures propagating within trench spaces following nearby explosions. This absence hinders the correlation between blast parameters, trench geometry, and reported injury cases, limiting our understanding of blast-related risks within trenches.
This paper addresses the critical aspect of blast propagation within trench systems, essential for evaluating potential blast injury risks to individuals within these structures. Through advanced computational fluid dynamics (CFD) simulations, the study comprehensively investigates blast injury risks resulting from explosions near military trenches. Employing a sophisticated computational model, the research analyzes the dynamic blast effects within trenches, considering both geometrical parameters and blast characteristics influenced by explosive weight and scaled distance.
The numerical simulations yield valuable insights into the impact of these parameters on blast injury risks, particularly focusing on eardrum rupture, lung injury, and traumatic brain injury levels within the trench. The findings elucidate distinct patterns of high-risk zones, highlighting unique characteristics of internal explosions due to confinement and venting dynamics along the trench. This study underscores the significance of detailed numerical modeling in assessing blast injury risks and provides a novel knowledge base for understanding risks associated with explosives detonating near military trenches. The insights gained contribute to enhancing safety measures in both military and civilian contexts exposed to blast events near trench structures.
