- 通过对现有混凝土构件受飞行物冲击作用的研究成果的分析，归纳并总结了全容式LNG储罐混凝土外罐受飞行物冲击作用的局部验算方法与要点。以某16万m3LNG储罐为例，进行了冲击效应的详细计算，计算结果表明，在质量为110 kg、等效直径为0.3 m、冲击初始速度为45 m/s的飞行物作用下，该混凝土外罐的截面厚度取值能够承受飞行物的冲击作用。
By analyzing and studying the results in existence of flying object impact effect on concrete components,the methods and key points for verifying calculation of the local effect of flying object impact on the concrete outer tank of a full-containment LNG storage tank are summarized.Taking the 160 000 m 3 fullcontainment LNG storage tank as an example,the details of calculating local effect of impact are introduced,and the results indicate that the thickness values of the roof and wall of this concrete outer tank suit to the impact effect of the flying object with mass of 110 kg,equivalent diameter of 0.3 m and initial impact velocity of 45 m/s.2013,4(4): 30-32 收稿日期：2012-2-5DOI：10.3969/j.issn.1001-2206.2013.04.008作者简介：李全光(1975-)，男，湖北大冶人，高级工程师，2001年毕业于武汉大学工程力学专业，硕士，现主要从事LNG储罐的设计计算工作。参考文献：
