根据多年来管线破坏事故统计和现有的检测数据,分析造成管线破坏的主要影响因素,利用SAS软件,采用Logistic回归分析方法对管线破坏数据进行回归分析,建立管线失效概率与生存环境的数学模型,用回归方程说明管线失效概率与主要影响因素之间的关系,揭示管线破坏现象的内在规律,为管线管理部门的决策提供重要依据。
Based on the statistics of pipeline damage accidents and the existing test data over the years, the main influencing factors of pipeline damage are analyzed. By using SAS software, logistic regression analysis method is used to conduct regression analysis of pipeline damage data and to establish the mathematical model of pipeline failure probability and living environment , Using regression equation to illustrate the relationship between the probability of pipeline failure and the main influencing factors and revealing the inherent law of pipeline destruction and providing an important basis for the decision of pipeline management department.
