本文提出了确定工程结构爆炸荷载的问题。在发生工业事故或恐怖袭击的情况下，在许多情况下需要确定必要的爆炸参数以确定结构的响应，优选地以简单且省时的方式。这样，经验关系可以用来估计爆炸载荷的选定参数。过去已经导出了许多经验关系，但并非所有关系都适用于不同类型的爆炸。本文通过经验关系对所选炸药的实验确定的选定爆炸参数进行了比较和验证。为了进行比较，使用了三种已验证且常用的计算程序（Kingery、Kinney、Henrych）和一种新推导的程序（PECH）。作为实验测量的一部分，确定了近场爆炸的小装药的冲击波爆炸参数。实验使用通用塑料炸药Semtex 10-SE。本文提出的比较研究结果表明，考虑这些程序对于可靠确定爆炸作用对建筑物的影响非常重要。
This paper presents the issue of determining the blast load on an engineering structure. In cases of industrial accidents or terrorist attacks, in many cases it is necessary to determine the necessary explosion parameters to determine the response of the structure, preferably in a simple and time-saving manner. In such a way, the empirical relationships can be used to estimate the selected parameters of the explosion load. Many empirical relationships have been derived in the past, but not all are suitable for different types of explosions. This article compares and validates experimentally determined selected explosion parameters for the chosen explosive with empirical relationships. For comparison, three already verified and frequently used calculation procedures (Kingery, Kinney, Henrych) and one newly derived procedure (PECH) were used. As part of the experimental measurements, blast wave explosion parameters for small charges were determined for near-field explosions. The general-purpose plastic explosive Semtex 10-SE was used for the experiments. The results of the comparative study presented in this article demonstrate the importance of taking these procedures into account for a reliable determination of the effects of blast actions on buildings.
