摘　　要：CNG加气站风险评价的一个重要方面是对其火灾爆炸失效后果进行评价。目前加气站燃烧爆炸事故的风险评估主要以预先危险性分析、故障树分析等定性风险分析方法为主。阐明了加气站事故损害的影响因素,包括一般工艺危险性和特殊工艺危险性分析。并对加气站火灾爆炸危险性作了全面的分析。在此基础上,对某CNG常规站采用指数评价法开展加气站火灾爆炸风险后果的定量评价,为站场定量风险评价研究工作奠定了基础。An important aspect of risk assessment for CNG filling station is the evaluation of fire and explosion consequence. At present the methods of risk evaluation are mostly qualitative-based, such as hazard analysis and fault tree analysis. The influencing factors of damage in the station are illustrated including ordinary technology hazards and special technology hazards. And the hazards of fire and explosion are analyzed. On that basis, the index method is used to carry out the evaluation of failure consequence for the CNG filling station. It would lay the foundation for station quantity risk assessment.
