The Groundwater Environmental Risks Assessment Based on Fuzzy Fault Tree Analysis Method to the Oil Pipeline
Ren Yu-feng · Environmental Science & Technology · 2013
In order to assess the groundwater environmental risks of the oil pipeline,established the oil pipeline's fault tree,and analyzed the main factors of the pipelines' failure,by the fuzzy probability of Triangular linear fuzzy function,and got the critical importance degrees according to the definition of critical importance degree of each basic event.Taking a period oil pipeline for example,predicted the pollutants migration under accident conditions based on the groundwater solute transport model,combining the buried pipelines' engineering characteristics and the hydro-geological conditions along the pipeline.It put forward some emergency preparedness and prevention-control measures,and provided a reference for other pipelines.
