Most of china natural gas pipeline passed through a variety of geological environment, the pipeline accidents happened frequently 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, reference fuzzy data theory, establish the model of geological disasters natural gas pipeline, and deal with the inconsistency for the same evaluation objects, make evaluation has more unity, and avoid the expertise and experience of the one-sided and subjective judgments brought results bias.
