同异反模式的管道土壤腐蚀综合评价
Integrated evaluation of the soil corrosion in pipeline in contrary identical discrepancy model
摘要
Abstract
In order to guarantee the transportation safety of the energy pipeline,reduce the occurrence of pipeline accidents,and improve the evaluation accuracy of the soil corrosion on pipeline,we select five kinds of evaluation factors,REDOX potential,sulfuric acid root ion content,water content,pH value,and average corrosion rate.The five kinds of multi-factor indexes of the soil corrosion on pipeline and the soil corrosion grade are made into a set pair with the set pair theory,determine the index weight by the entropy method,calculate the distance of the contact degree between the forecast system to test and the classification system in the contrary identical discrepancy model according to the choice of the nearly principle of the clustering analysis thought.Taking the corrosion buried piece data of the East gas pipeline Liang ping section in Sichuan as an example,choose eight sets of data as the training sample structure evaluation model,the other 8 sets of data as the test sample,the model evaluation results for the test sample conform to the actual situation.It provides a methodological guidance for the soil corrosion evaluation.关键词
