D-S Evidence Theory in the Mountainous Gas Pipeline Evaluation of Application
2011
Most of China's natural gas pipeline passed through a variety of geological environment. The pipeline accidents happen frequently and are caused by landslides and collapse. The reliability of the current research on mountain pipe buried natural gas pipeline is limited to defects, almost empty, and on the judgment of the hazard is confined to the traditional reliability evaluation method. This paper uses D-S evidence theory to the mountain pipe for reliability analysis, references fuzzy data theory, establishes the model of geological disasters in natural gas pipeline, deals with the inconsistency for the same evaluation objects, makes evaluation and has more unity, and avoids the expertise and experience of the one-sided and subjective judgments resulting in bias.
