- 摘要:
- 〗随着我国现代化进程的加快，管道建设与电力设施的建设呈现出高速发展的局面。然而，高压交流、直流电力设施对埋地管道存在着严重的干扰腐蚀情况。采用正交实验的方法，重点关注交流腐蚀对埋地管道的影响因素，并得出其相互间的数学关系，然后综合腐蚀机理以及正交实验结果，通过正交实验的筛选过程确定主要因素、次要因素以及影响较小的因素，选择合理的指标，运用故障树分析、专家咨询以及二手资料的分析法，并参考国内外的研究现状，全面吸收、归纳、重组、增删现有的评价指标，建立埋地管道交流腐蚀风险等级评估指标体系，运用模糊数学综合评价的方法全面系统的评估交流腐蚀风险等级，从而为埋地管道的安全管理提供可靠的数据。
- Abstract:
- With the acceleration of modernization process in China, the construction of pipeline and power facilities present rapid development. However, it must pay close attention to the serious interference corrosion of buried pipeline in high voltage current, direct current electric power facilities, and so on. For pipeline accident by 80% occurring in underground, on the basis of full understanding of corrosion mechanism, the orthogonal design method was applied, focusing concern effect factors of AC corrosion on buried pipeline , and obtained its mutual mathematics relationship. Then, combining corrosion mechanism and orthogonal experimental results , the main factors , secondary factors, and less impact factor were determined by the orthogonal experiment screening process, choose the reasonable indicators, while by using fault tree analysis, expert advice, and secondary data analysis, as well as reference to the study summarization both at home and abroad, comprehensive absorption, induction, reorganization, additions and deletions were conducted on existing evaluation indicators, those little influance factors were deleted to establish risk grade assessment index system of AC corrosion on buried pipeline, and comprehensive evaluation method of fuzzy mathematics was applied on systematic evaluation of AC corrosion risk grade, in order to provide reliable data for security management of duried pipeline.
