Systematic Structural Analysis of Buried Urban Gas Pipeline Disaster in Karst Area
摘要
Abstract
In order to conduct a systematic structural analysis of buried urban gas pipeline in karst areas,combined with disaster system theory,the disaster system of gas pipelines in buried urban gas pipeline in karst areas is deconstructed into four subsystems,including disaster inducing environment,disaster factors,disaster bearing body and disaster situation.By clarifying the structural characteristics of the disaster system,this study aims to provide theoretical basis for disaster prevention and control of gas pipelines in buried urban gas pipeline in karst areas.Research shows that the disaster inducing environment is the breeding ground for disaster factor,and its activity is closely related to the unsafe state of personnel,pipelines,and the environment,as well as management vulnerabilities.The disaster factor is the direct energy source that harms the disaster bearing body and leads to the disaster situation,mainly including fire thermal radiation and explosion shock wave overpressure.The two can appear alone,or induce and aggravate secondary disasters under chain conduction effects.The disaster bearing body is the direct target of disaster factors,mainly including society,economy and nature disaster bearing body.They are closely related and interactive.The disaster situation is a measure of the degree of disaster harm.It corresponds to the disaster bearing body,and depends on the influence degree of disaster factors on personnel casualties,economic losses,and environmental damage.关键词
