摘要/Abstract

摘要： 为预防油气管道运营过程中发生坡面水毁地质灾害,对油气管道进行坡面水毁危险性评价是必要的。依据可拓理论建立坡面水毁危险性评价物元模型,计算出各评价指标关联函数,采用熵权法对各评价指标进行赋权,最后得出危险等级。选取河西走廊高台地区的11条坡面冲沟作为评价对象,将该方法评价结果与管道公司软件评价结果进行对比。结果表明:就高台地区11条坡面冲沟危险性而言,基于熵权法与可拓理论相结合得到的管道坡面水毁危险性评价结果与用管道公司的软件得到的评价结果相吻合。

Abstract: In order to prevent flood damage at slope of oil and gas pipelines, it's essential to assess the risk of flood damage. A matter-element model was built for assessing the risk by the extension theory. Correlation functions were calculated for the evaluation indexes. By using the entropy method, values of weight were assigned to the evaluation indexes. So the level of risk was assessed. Then eleven slope gullies located at Gansu Corridor Gaotai were selected as evaluation objects. A comparison was made between the evaluation results calculated by this method and those calculated by using the software of the pipeline companies. The results indicate that the evaluation results obtained by using the extension theory based on the entropy method conform with those obtained by using the software for those eleven slope gullies.

Key words: pipeline, flood damage at slope, assessment of risk, extension theory, entropy method
