摘要
为准确评价并行管道的风险等级,统计了2004—2024年有关并行管道风险的国内知网文献,通过聚类、共现和突变的知识图谱分析,确定了国内有关的研究进展和演进趋势,获取了指标体系的构建方式和方法,并结合G1法和危险度确定不同类型并行管道的综合风险水平。结果表明,该领域的高频关注点集中在并行间距、环境因素、腐蚀和管道特性方面,研究对象主要为油气并行管道,且多采用赋权法进行风险评价;并行间距对并行管道风险的影响最大,其次为敷设环境;隧道段并行管道的危险度最大,其次为同桥段并行管道和埋地段并行管道。研究结果可反映并行管道的真实风险水平,提出的方法合理、有效。
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.
