摘　　要：为了准确计算城市环境中加油站的安全距离并进行安全评估,针对城市中一级加油站蒸汽云爆炸灾害效应开展分析,基于TNT当量法和Roberts点源模型,计算距离加油站不同距离上的爆炸波超压和火球热辐射通量。依据相应的伤害准则,系统评估了灾害效应,并与已有试验数据和规范进行对比验证和分析。研究结果表明,城市一级加油站的爆炸安全距离为37 m,热辐射安全距离为52 m。The effect of vapor cloud explosion of the first - level gas station is analyzed in this manuscript. Based on the TNT equivalent method and Roberts point source model, the blast overpressure and fireball thermal radiation flux in different distances from station are calculated. A systematical evaluation of the disaster effects is conducted accord- ing to the corresponding damage criterion, and also a comparison with the existing experimental data is carried out. It is indicated that the explosion and thermal radiation safety distance of the first - level gas station are 37 m and 52 m, respectively.
