摘要

2020年贝鲁特港口硝酸铵爆炸造成了黎巴嫩首都贝鲁特历史上最严重的人员生命和财产损失。本研究以爆炸现场附近高层建筑的爆炸损伤为研究对象,通过理论计算、SFPE《消防工程手册》的爆炸损伤比例尺和爆炸后真实图像的对比,分析了超压/距离关系。研究中估计的三硝基甲苯当量爆炸尺寸为713吨。研究中包括了六座不同距离的高层建筑,并进行了分类。结合Kingery-Bulmash爆破参数在线计算器,采用Baker、Sadovski和Alonso方法的理论超压模型和爆破操作超压模型。观察到的超压值范围很广。将理论超压模型的计算值纳入爆炸损伤比例尺,并与实际图像进行比较,主要在距离较近的建筑物上表现出较好的匹配。

Tall buildings damage in Beirut ammonium nitrate explosion

Tall buildings damage in Beirut ammonium nitrate explosion

The 2020 Beirut port’s ammonium nitrate explosion led to the most severe damage, in terms of human lives and property loss, ever seen in the history of Beirut, the capital of Lebanon. The current study focuses on the blast damage of tall buildings near the explosion site and analyses the overpressure/distance relationship based on the comparison between theoretical calculations, the blast damage scale from the SFPE Handbook of Fire Protection Engineering, and real post-explosion images. The estimated trinitrotoluene equivalent blast size for the research is assumed to be 713 tons. Six tall buildings at different distances were included in the research and divided into categories. Theoretical overpressure models of Baker’s, Sadovski’s, and Alonso’s methods and Blast Operational Overpressure Model were used in combination with the Kingery–Bulmash Blast Parameter online calculator. A wide range of overpressure values were observed. The calculated values from the theoretical overpressure models were incorporated into the blast damage scale and compared with the real images, with the better match being mainly demonstrated for buildings at closer distances.

期刊介绍: Shock Waves provides a forum for presenting and discussing new results in all fields where shock and detonation phenomena play a role. The journal addresses physicists, engineers and applied mathematicians working on theoretical, experimental or numerical issues, including diagnostics and flow visualization. The research fields considered include, but are not limited to, aero- and gas dynamics, acoustics, physical chemistry, condensed matter and plasmas, with applications encompassing materials sciences, space sciences, geosciences, life sciences and medicine. Of particular interest are contributions which provide insights into fundamental aspects of the techniques that are relevant to more than one specific research community. The journal publishes scholarly research papers, invited review articles and short notes, as well as comments on papers already published in this journal. Occasionally concise meeting reports of interest to the Shock Waves community are published.
