【摘要】：城市作为一个复杂的系统,其发展离不开天燃气等动力能源,城市燃气管网运行存在来至人、设备、环境以及管理等各方面的风险隐患耦合作用,同时随着城市社会经济的发展,其凸显脆弱性,燃气管网各种风险相互耦合并引发事故灾难,将会对城市造成极大的破坏,相关事故在国内外屡见不鲜。为了减少城市燃气管网灾害事故的发生,从风险耦合的角度出发,对多因素耦合作用下城市燃气管网灾害风险的研究现状进行文献分析,从而发掘已有研究存在的不足。通过对国内外城市燃气管网耦合灾害风险的大量相关文献进行分析,发现过往研究存在以下问题:1当前对多因素耦合作用下的城市燃气管网的灾害风险作用机理进行的研究较少;2缺乏对城市燃气管网多因素耦合灾害风险演化规律的研究;3对城市燃气管网多因素耦合灾害风险评估模型的研究也较少;4也没有对城市燃气管网多因素耦合灾害风险的动态管控策略开展研究。针对此四方面的问题,最后提出了在城市复杂环境下,燃气管网面对多风险因素耦合作用时的研究方向,对多因素耦合灾害风险理论发展以及城市安全运行和管理起到促进作用。
[Abstract]:City as a complex system, its development can not be separated from natural gas and other dynamic energy, urban gas pipeline network operation to people, equipment, environment and management and other aspects of the coupling role of risks and hidden dangers. At the same time, with the development of social economy, the vulnerability of gas pipeline network is highlighted. The coupling of various risks of gas pipe network and the accident disaster will cause great damage to the city, and the related accidents are common at home and abroad. In order to reduce the occurrence of disaster accidents in urban gas pipeline network, the present situation of disaster risk research in urban gas pipeline network under the action of multi-factor coupling is analyzed from the point of view of risk coupling, so as to explore the shortcomings of existing research. Based on the analysis of a large number of related documents on coupling disaster risk of urban gas pipeline network at home and abroad, It is found that the following problems exist in the past researches: 1. At present, the research on the mechanism of disaster risk of urban gas pipeline network under the action of multi-factor coupling is less. 2 lack of the evolution law of multi-factor coupling disaster risk of urban gas pipeline network. There are few studies on the multi-factor coupled disaster risk assessment model of urban gas pipeline network and no research on the dynamic control strategy of multi-factor coupling disaster risk in urban gas pipeline network. In view of these four problems, the research direction of gas pipeline network in the face of multi-risk coupling action in the complex urban environment is put forward at the end of the paper. It can promote the development of multi-factor coupling disaster risk theory and the safe operation and management of city.
