大量的科学工作致力于测量和了解爆炸的影响，从而开发了快速预测爆炸载荷参数的半经验方法。其中最著名的方法被称为 Kingery 和 Bulmash 方法，它利用了从几十年来进行的中型到大规模实验测试的汇编中得出的多对数曲线。然而，尽管一些研究人员一致报告一致程度很高，但对于这种方法的准确性和有效性仍然没有达成普遍共识。此外，尚不清楚爆炸载荷是否可以被认为是确定性的，或者它是否本质上是可变的，这种可变性的程度以及观察到这些变化的范围和规模。本文批判性地回顾了历史和当代的爆炸实验，包括使用 RDX 和 PETN 炸药进行的新生成的竞技场测试，以证明使用半经验方法预测爆炸载荷参数的准确性。
A significant amount of scientific effort has been dedicated to measuring and understanding the effects of explosions, leading to the development of semi-empirical methods for rapid prediction of blast load parameters. The most well-known of these, termed the Kingery and Bulmash method, makes use of polylogarithmic curves derived from a compilation of medium to large scale experimental tests performed over many decades. However, there is still no general consensus on the accuracy and validity of this approach, despite some researchers reporting consistently high levels of agreement. Further, it is still not known whether blast loading can be considered deterministic, or whether it is intrinsically variable, the extent of this variability, and the range and scales over which these variations are observed. This article critically reviews historic and contemporary blast experiments, including newly generated arena tests with RDX and PETN-based explosives, with a view to demonstrating the accuracy with which blast load parameters can be predicted using semi-empirical approaches.
