摘　　要：影响管道安全的因素很多,事故的风险识别及事故后果的预测存在一定难度。如何保证完好性投资首先用到具有高风险的管线上,一直是一个重要的问题。提出了事故次数、管龄、期望寿命期、输送量、承压裕量、地区等级、相对风险值、价值指数八个比较指标,采用灰色关联分析法来对待维修整改的项目进行优先排序。灰色关联分析优先排序的结果可供管道公司为下一步提出维修整改的时间表作参考,是作出合理决策的有效依据。Due to many factors affecting pipeline safety,it is difficult to discern pipeline risk and predict accident consequence.How to guarantee using the integrity investment on risky pipeline at first is a question not easy to deal with.Such 8 comparative indexes are put forward as accident times,pipeline age,expected pipeline life-span,transportation capacity,pressure-bearing allowance,area grade,relative risk value,value index.Gray Relation Analysis Method is applied to prioritizing pipeline maintenance and reformation.This method is beneficial for pipeline companies to prepare pipeline maintenance and reformation sechedule and make reasonable decisions.
