Abstract


West-East project is a national key projects of energy , charged with the task of national economic sustainable development , with important political and economic significance . However, due to pipeline long lines across the Chinese territory of the whole thing , will encounter a variety of geological hazards along the way , once suffered damage will cause unpredictable consequences . In order to ensure the integrity of the pipeline , the disaster did not occur before the need for the pipeline for geological disaster risk assessment in order to develop prevention programs to ensure the normal operation of the pipeline . Based on the existing theory of disaster risk assessment were identified for natural gas geological disaster risk assessment theory and method . As the domestic focus is on hazard analysis and evaluation of the causes of disasters , vulnerability assessment and disaster risk and vulnerability comprehensive assessment of both the relatively small paper in the entire history of geological hazards along the pipeline based on the analysis , select the typical characteristics of Shaanxi disaster as evaluated by the Shaanxi section along the geological environment and economic profile of the analysis , selection and material flow and other landslides vulnerability , economic vulnerability , social vulnerability as a hazard and disaster vulnerability an evaluation factor , select the effect of topography, climate conditions , geological conditions , building density , along the industrial prosperity , population density , etc., as two evaluation factors , the establishment of the zone hazard evaluation models and Yi damage assessment model, using integrated AHP effectively combine the two , geological disasters affecting pipelines factors were evaluated to determine the impact of various factors on the weight of the pipeline and the degree of risk , and to evaluate the results of the proposed pipeline encounters geological disaster prevention countermeasures. By studying the results showed that: This paper used the geological disaster risk assessment theory and methods suitable for natural gas project , the results of the assessment consistent with the actual engineering surveys for pipeline management has certain guiding significance.
