The paper presents unique blast experiments in reference to scientific literature and official standards. Experimental scenarios reflect a hypothetical realistic combat situation of a human being covered from a blast wave behind a rigid building corner. In the scenario assumed, the overpressure loads affect the lungs while the person is standing or the eardrums while the person is kneeling at the aiming position. The paper presents 27 free-field experiments measuring the overpressure loads. All the measurements were taken behind the right angle of the rigid wall. Two masses of TNT were considered: 200 g and 400 g. In the selected cases, a low test-to-test variability of the measured data was observed. Detailed plots of overpressure versus time are presented for various distances behind the building corner and TNT charge masses. Peak overpressure versus positive impulse plots are also demonstrated. Furthermore, the safety thresholds regarding different locations behind the building corner are defined for the considered explosive masses.

建筑物转角后方爆破荷载试验研究

本文参考科学文献和官方标准介绍了独特的爆破实验。实验场景反映了一个假设的现实战斗情况，一个人被一个刚性建筑角落后面的冲击波覆盖。在假设的场景中，超压负荷会影响人站立时的肺部或人跪在瞄准位置时的耳膜。本文介绍了 27 个测量超压载荷的自由场实验。所有测量均在刚性墙的直角后方进行。考虑了两种质量的 TNT：200 克和 400 克。在选定的案例中，观察到测量数据的测试间可变性较低。针对建筑物角落和 TNT 装药质量后面的不同距离，显示了超压与时间的详细关系图。还展示了峰值超压与正脉冲图。此外，针对所考虑的爆炸物质量定义了建筑物拐角后面不同位置的安全阈值。
