油气爆炸压力下海洋平台防爆墙结构形式研究

摘要

The simulated method is used in researching on the blast wall structure of offshore platform under explosion pressure of flammable gases. The paper studied the energy absorption for the different ratio of major axis and minor axis for the half elliptic blast wall. The effective for anti-blast was not better if the ratios of major axis and minor axis were larger and smaller or not. When the ratio is 0. 25, the half elliptic blast wall had the best effective for anti-blast.%通过数值方法对海洋平台在内部油气爆炸作用下,其爆炸舱室的防爆墙结构进行研究.分别研究了半椭圆结构形式的防爆墙6种不同短轴和长轴比对结构吸能的影响.计算结果表明,半椭圆防爆墙结构的短轴和长轴比偏大和偏小,防爆效果都不理想;当短轴和长轴比为0.25时的半椭圆防爆墙结构具有最佳的防爆效果.
