埋地燃气管道泄漏失效与数据库研究进展

摘要

The researches on gas pipeline accidents are disscussed based on the leakage failure of buried gas pipelines and the pipeline database.The leakage failure of gas pipelines is studied in terms of the accident causes,leakage detection and risk assessment.The structure and functions of pipeline database at home and abroad are summarized,and the necessity and significance for developing the pipeline database are pointed out.%从埋地燃气管道泄漏失效和管道数据库两个方面论述了燃气管道事故的研究现状.并分别从事故原因、泄漏检测以及风险评估三个角度对燃气管道泄漏失效事故研究展开讨论；同时,通过总结国内外已有管道数据库的结构和功能,指出我国发展管道数据库的必要性和重要性.
