摘　　要：通过钢筋混凝土-泡沫夹层-钢板混凝土复合结构的抗爆试验，对夹芯泡沫材料的主要特点及其在复合结构中的作用机理进行了研究。结果表明：泡沫夹层对冲击波具有很好的衰减作用，泡沫夹层的存在可使爆炸产生的相对集中的局部荷载转化为分布趋向均匀的整体荷载，从而使内层结构处于有利的受力状态。本文的研究可为夹芯泡沫材料在防护工程中的应用提供技术参考。Based on the experiment of an anti-blast composite structure composed of reinforced concrete, steel plate concrete and foam sandwich, the main properties and working mechanism of the foam sandwich materials in the anti-blast composite structure are studied. Results show that the foam interlayer has very good blast-wave attenuation function. This property of the foam can transform the explosively - generated concentrated pressure into a relatively evenly distributed global pressure, thus making the inner structure in a safe stress state. The research in this paper could provide technical reference for the application of foam sandwich materials in protective engineering.
