摘　　要：为实现在相对固定条件下各种爆炸现象、结构或材料抗爆特性等的实验研究,设计了室内大尺寸爆炸试验装置并考虑了减振措施,该爆炸试验装置是地下半封闭式分层复合结构,复合结构层由钢板、钢筋混凝土和砂隔振层组成。运用一维弹性平面应力波理论对爆炸试验装置的抗爆性能进行了分析,并对分层复合结构的抗层裂和震塌效应进行了研究。结果表明,该装置可满足工程抗爆实验的要求。In order to realize experimental investigation of explosive phenomena, blast-resistant performance of structure or material at stable environment, the large-scale equipment used for indoor blast test was designed with vibration reducing method. The equipment is a half-closed multiple layered underground structure, which is made up with steel, reinforced concrete and sand layers. The blast-resistant performance of the equipment was analyzed based on one-dimensional elastic plane stress wave theory and research of the layer-crack and collapse of the multiple layered structure was carried out. The results show that the equipment can satisfy the demand of engineering blast-resistant test.
