【摘要】 由于受经费和地质条件的限制,人防工程不可能无限制地增加防护层厚度,因此利用分层结构对爆炸波的衰减和弥散效应,通过试验研究分配层分层结构对核爆炸荷载的防护效果是十分必要的.利用平面装药爆炸模拟核爆炸的加载技术,进行了分配层分层结构对核爆炸荷载防护效果的大比尺相似模拟野外化爆试验,通过4个精心设计的不同分层结构的平面装药加载试验,证明了分配层分层结构对核爆炸的防护效果明显优于单层结构.更多还原

【Abstract】 Because of the restrict by funds condition and geologic setting,it is impossible for the defense layer of civil air defense works to be thickened without limit,therefore in view of the damping effect and dispersion effect of layered structures on blast waves,it is necessary to investigate the layered structure’s defense effect of civil air defense works’ distribution layer against nuclear explosive loadings.A series of large-scale analogy-simulation tests were conducted on layered structure’s defense effect of distribution layer against nuclear explosive loadings by utilizing the loading technology of nuclear explosion analogy with plane charge explosive.The layered structure defense effect of a distribution layer against nuclear explosive loadings is better than that of a single-layer structure,as demonstrated by four subtly designed plane charge explosive loading tests with different kinds of layered structures.更多还原
