摘　　要：针对我国特大型LNG储罐结构设计在爆炸与冲击荷载作用下性能分析资料(主要由国外设计)不完善等问题,回顾常规爆炸冲击荷载研究方法;总结国内外对与特大型LNG储罐类似结构—核反应堆安全壳的抗爆研究成果,以期对该类储罐的抗爆研究提供参考;结合国内外对储罐类结构的抗爆设计及研究现状,提出相关研究存在问题及发展趋势,期望能对我国该类储罐的安全性研究与国产化设计提供参考。As China's demand for liquefied natural gas (LNG) and import increase year by year, to build more LNG terminals to meet the requirement becomes extremely urgent. Extra-large LNG storage tank belongs to a lifeline project. If the tank is attacked with conventional weapons, it has unpredictable consequences. However, the LNG storage tank design method is controlled by few developed countries, and all extra-large LNG projects in China are designed and constructed by foreign companies with no technology transfer, this situation leads to lack of necessary study and reliable information in China. Here, the studying methods for conventional weapons and explosion load were outlined. Then, the antiknock design and the study results for nuclear reactor containment similar to LNG storage tank were summarized to provide references for the antiknock study on the latter. Finally, the existing problems and the trend of development in this field were presented combining the current studying status about the antiknock design of extra-large LNG storage tank home and abroad. Some suggestions were provided for the safety study and the self-design of extra-large LNG tanks.
