摘要
随着我国液化天然气（LNG）的需求量与进口量逐年增加，沿海地区许多城市已陆续开始采用特大型LNG接收站接收、储存和供应天然气。液化天然气储罐类设施属于生命线工程，其安全性至关重要，一旦承受非常规荷载如武器袭击或飞行物撞击等，灾难性的后果不堪设想。然而目前特大型LNG储罐的结构设计基本由国外公司承担，有关其在爆炸荷载和冲击荷载作用下性能的分析资料尚不完善。针对这一问题，首先回顾了常规爆炸冲击荷载的研究方法；然后总结了国内外对于与特大型LNG储罐相类似的结构——核反应堆安全壳的抗爆研究成果，以期对特大型LNG储罐的抗爆研究提供一定的参考；最后结合目前国内外对储罐类结构的抗爆设计和研究现状，提出了目前相关研究存在的问题和发展趋势，期望能对我国特大型LNG储罐的安全性研究和国产化设计提供参考。
Abstract
As China’s demand and import for liquefied natural gas (LNG) increased year by year, to build more LNG terminal matching for the requirement is becoming extremely urgent. Extra-large LNG storage tank is belong to lifeline project. If the tank is attacked by conventional weapons, it has unpredictable consequences. However, due to LNG storage tank design method controlled by the few developed countries abroad, and all extra-large LNG projects in China are designed and constructed by foreign companies with no technology transfer, which lead to lack of necessary research and reliable information for China. Outlines the research methods of the conventional weapon and explosion load; then summarizes the antiknock design and research results for nuclear reactor containment which is similar to LNG storage tank, in order to provide references for the antiknock research of the latter; finally, proposes the problem and research demand combined the current research of extra-large LNG storage tank, and expects to provide some assistance to the security research and extra-large LNG tank design research of China.
