摘　　要：本文根据多年来管线破坏事故统计和现有的检测数据,统计分析造成管线破坏的因子。利用SAS软件,采用PRINCOMP过程对管线破坏数据进行主成分分析,将彼此相关的一组管线破坏因子指标变量转化为彼此独立的一组新的指标变量,最后,建立管线破坏概率与生存环境的数学模型,对破坏因子进行主成分分析。根据分析结果,揭示管线破坏现象的内在规律,为管线管理部门提供决策依据。According to the pipeline damage accident statistics over the years and the existing test data,this article counted and analyzed pipeline damage factors.By using SAS software and PRINCOMP process,the data of principal components for pipeline failure were analyzed,and the relation damage factors were converted into independence factors.Finally,a mathematic model of the pipeline failure probability and the living environment,for the damage factors to carry on the principal component analysis.According to the results,the inherent law of pipeline failure phenomenon would be revealed,which could provide the reference for the pipeline management.
