Risk Assessment Model and Application for the Urban Buried Gas Pipelines
With the increasing popularization of the urban buried gas pipeline, accidents are occurred usually.Once the pipeline failed in operation,it can produce leakage serious consequence, as the fire and explosion and so on, and the consequence involves security of resident life and property loss, and affects the social stability, therefore the safe operation of urban buried gas pipeline is extremely important.The factors effected failure of pipeline are complicated and varied, and most of them have getting fuzzy because of complicated underground environment in city,meanwhile, the factors caused failure consequence are uncertain because of various states on ground.Article takes risk study on buried gas pipeline in service more in a city as aa example, and the failure possibility and failure consequence of buried gas pipeline are expressed and evaluated with fuzzy language and fuzzy comprehensive assessment method, and illustrated the risk grade of buried gas pipeline with risk matrix according to API, and obtained risk grades of various pipe element of pipeline,some measures are adopted according to the different risk grades to perfect integrality management of pipeline, and to decrease the operation risk of pipeline, and to ensure operation safely of the urban buried gas pipeline.
