摘要
随着我国城镇燃气使用的普及,燃气爆炸事故也大量增加。目前我国针对民宅燃气爆炸所进行的防爆研究却很少,许多工作都有待于进一步开展。文章结合几起较为严重的燃气爆炸事故,概括了燃气爆炸灾害特点及其对建筑结构的损伤程度;结合燃气爆炸机理和民用住宅自身特点,详细讨论了建立民宅燃气爆炸力学模型的主要思路;以国内外防爆研究现状为基础,提出了民用建筑可能的防护加固措施;讨论了利用数值模拟技术进行研究的关键技术难题;最后列举了有待于进一步研究的内容。
With the increase of domestic gas consumption in cities and towns, gas explosion disasters arise more often than before. However, little researches have been done on the anti-explosion research about the gas explosion happened in civil buildings. Several severe accidents are enumerated at first, characteristics of the disaster and its damage to buildings are also summarized. Then, the mechanism of the gas explosion and the characteristics of civil house are analyzed. And the main idea to establish the mechanical model in a room is discussed in detail. Based on the present research status at home and abroad, some protection and strengthening measures are put forward. Some key problems of the numerical simulation technology are discussed. At last, some further research issues in the future are presented.
