摘要
简要介绍埋地燃气管道的模糊综合评价方法,阐述了埋地燃气管道风险影响因素的模糊评价集及风险影响因素权重的具体确定方法.针对某市某段埋地煤气管道,进行管道失效后果因素的模糊评判,得到该管道失效后果因素的风险值.对比分析了模糊综合评判结果与API581失效后果定性分析结果,确证了管道失效后果模糊综合评价的可行性.
The method of fuzzy comprehensive evaluation is used into the urban buried gas pipeline in this paper. Fuzzy evaluation factor sets and weights of risk factors in gas pipeline have been made sure by the concrete methods. The severity of the failure consequences about the buried gas pipeline in a city have been evaluated by fuzzy comprehensive assessment. Comparing the analytical results of fuzzy comprehensive assessment method with API581 about failure consequence systems, the applicability of evaluating the serious degree of the pipeline failure consequence using fuzzy comprehensive assessment method has been certified.
