Construction and analysis of parallel pipeline risk index system based on knowledge graph
To accurately evaluate the risk level of parallel pipelines,this paper collected domestic literature on CNKI related to parallel pipeline risk from 2004 to 2024 and determined the domestic research progress and trend through the clustering,co-occurrence,and mutation of the knowledge graph.After obtaining the construction method of the index system from the above process,the paper combined the G1 method and risk degree to determine the comprehensive risk level of different types of parallel pipelines.The results show that the high-frequency concerns in this field are parallel spacing,environmental factors,corrosion,and pipeline characteristics.The research objects are mainly oil and gas parallel pipelines,and the risk assessment is mostly carried out by the weighting method.Parallel spacing has the greatest influence on parallel pipeline risk,followed by the laying environment.The risk of parallel pipelines in the tunnel section is the highest,followed by those in the bridge section and buried section.The research results can reflect the real risk level of parallel pipelines,and the proposed method is reasonable and effective.
