岩溶区燃气管道灾害系统多因素耦合作用机理研究
Study on the Multifactor Coupling Action Mechanism of Gas Pipeline Disaster System in Karst Area
摘要
Abstract
Based on the disaster system theory,from the systematic perspective of disaster pregnant environ-ment,disaster factors,disaster bearing body and disaster condition,the system dynamics model is used to explore the coupling relationships within and among subsystems of the gas pipeline disaster system in karst area.Consider-ing the differential transmission path among multiple factors,the action mechanism and influence rules of multiple factors coupling in the disaster evolution process are deeply analyzed.The results show that:The activity of disaster pregnant environments is closely related to the unsafe state of personnel,pipelines,and the environment,as well as management vulnerabilities;the risk of disaster factors is affected by the combined effects of the probability,inten-sity,scope,and duration of fire and explosion hazards;the vulnerability of disaster bearing body is affected by the coupling of society,economy and nature disaster bearing body;the severity of the disaster includes three dimen-sions:the degree of casualties,the degree of economic losses,and the degree of environmental damage.The incu-bation and evolution of gas pipeline disasters in karst areas is the result of the combined action of four subsystems.The coupling between two or three subsystems represents different stages of disasters,while the coupling of four subsystems describes the entire disaster process.关键词
