摘　　要：为研究埋地给排水管道在武器打击下的破坏效应,设计并开展了砂土中埋深1.5 m的给排水管道抗爆性能试验,在试验基础上利用有限元软件AUTODYN对埋地管道在外爆荷载下的毁伤效应进行数值计算,得到不同比例爆距下的管道变形程度,并结合标准给出安全阈值。In order to investigate the damage effects of buried drainage pipelines under weapon strikes,anti-explosion performance tests were designed and conducted on pipelines buried 1.5 meters deep in sand.Based on these experiments,numerical calculations of the damage effects on the buried pipelines subjected to external blast loads were performed when using the finite element software AUTODYN.The study obtained the deformation levels of the pipelines at various scaled distances and provided safety thresholds in conjunction with industry standards.
