摘　　要：以管道输送天然气泄漏情况为模型,计算了气体泄漏以后的扩散范围和泄漏量,对火灾燃烧和爆炸后的伤害范围进行了量化分析,提出了参考风险评价结果确定安全距离,以及将普通玻璃更换为防爆玻璃,建设防护墙等建议。Taking the gas leakage in pipeline transportation as a model, the diffusion range and the leakage rate of leaked gas are calculated. The damage range of the fire caused by the burning and explosion of the leaked gas is quantitatively analyzed. A safe distance is determined according to the risk assessment results, and some suggestions such as replacing the ordinary glass with explosion-proof glass, building protective walls etc. are proposed.
