Blast barriers are commonly used for protecting critical infrastructure from blast effects. While rigid blast walls are the most frequently used barrier type, they are often unattractive and obtrusive. It is therefore practical to consider the use of natural barriers. The applicability of trees as natural blast barriers has not been studied widely. Apart from several recent studies investigating the performance of hedges using small explosive charges and large-scale high-explosive forest blowdown studies from the 1950s-1960s, no other published results on the mechanical response of vegetation and its blast wave mitigation potential are found in the open literature. This paper presents the experimental results of the interaction of far-field blast waves with trees aimed to evaluate the potential of trees in protecting infrastructure targets from blast threats. Full-scale trees were exposed to simulated far-field blast loads generated in an Advanced Blast Simulator. The dynamic structural response of the Juniperus Spartan trees subjected to blast wave and their blast sheltering potential were investigated. This paper revealed the potential for trees in attenuating far-field blast waves and shelter target structures. A numerical model based on Computational Fluid Dynamics was developed in ANSYS FLUENT to reveal the blast mitigation mechanism of barriers against far-field blast loads. The model was also used to explain experimental observations.

防爆屏障通常用于保护关键基础设施免受爆炸影响。虽然刚性防爆墙是最常用的屏障类型，但它们通常没有吸引力和突兀。因此，考虑使用天然屏障是切实可行的。树木作为天然爆炸屏障的适用性尚未得到广泛研究。除了最近的几项研究使用小型炸药对树篱的性能进行调查和 1950 年代至 1960 年代的大规模高爆森林排污研究外，没有其他已发表的关于植被机械响应及其冲击波缓解潜力的结果在开放文学。本文介绍了远场冲击波与树木相互作用的实验结果，旨在评估树木在保护基础设施目标免受冲击波威胁方面的潜力。全尺寸树木暴露在高级爆炸模拟器中生成的模拟远场爆炸载荷下。研究了Juniperus Spartan 树木在冲击波作用下的动态结构响应及其避雷潜力。本文揭示了树木在衰减远场冲击波和掩蔽目标结构方面的潜力。在 ANSYS FLUENT 中开发了基于计算流体动力学的数值模型，以揭示屏障抵抗远场爆炸载荷的爆炸缓解机制。该模型还用于解释实验观察。全尺寸树木暴露在高级爆炸模拟器中生成的模拟远场爆炸载荷下。研究了Juniperus Spartan 树木在冲击波作用下的动态结构响应及其避雷潜力。本文揭示了树木在衰减远场冲击波和掩蔽目标结构方面的潜力。在 ANSYS FLUENT 中开发了基于计算流体动力学的数值模型，以揭示屏障抵抗远场爆炸载荷的爆炸缓解机制。该模型还用于解释实验观察。全尺寸树木暴露在高级爆炸模拟器中生成的模拟远场爆炸载荷下。研究了Juniperus Spartan 树木在冲击波作用下的动态结构响应及其避雷潜力。本文揭示了树木在衰减远场冲击波和掩蔽目标结构方面的潜力。在 ANSYS FLUENT 中开发了基于计算流体动力学的数值模型，以揭示屏障抵抗远场爆炸载荷的爆炸缓解机制。该模型还用于解释实验观察。本文揭示了树木在衰减远场冲击波和掩蔽目标结构方面的潜力。在 ANSYS FLUENT 中开发了基于计算流体动力学的数值模型，以揭示屏障抵抗远场爆炸载荷的爆炸缓解机制。该模型还用于解释实验观察。本文揭示了树木在衰减远场冲击波和掩蔽目标结构方面的潜力。在 ANSYS FLUENT 中开发了基于计算流体动力学的数值模型，以揭示屏障抵抗远场爆炸载荷的爆炸缓解机制。该模型还用于解释实验观察。
