北京市埋地燃气管道安全状况评估系统研究

埋地管道失效引起的突发事故会造成严重的财产损失、人员伤亡和环境破坏，针对管道的事故可能性进行评估．可以明确影响管道安全的主要因素．采取有效的措施减小事故的发生。基于安全评估思想和可靠的数学模型，对管道的腐蚀破坏、外力破坏和误操作破坏进行评估，对含缺陷管道进行剩余强度评价和剩余寿命预测，编制了基于GIS平台的评估软件“北京市埋地燃气管道安全状况评估系统”。利用现场检测数据及调查结果进行安全状况等级的评估，评估结论可靠，能直观显示管道的安全等级并提示薄弱环节，提供维护建议，对评估内容和结果适时进行统计分析，操作简单，实用性强。

Study on Gas Pipeline Safety Evaluation System

Sudden Accidents due to the failure of the buried pipeline can cause great dameges, such as property loss, per- sonal injury or loss of life, and detroy to the envirement. Evaluation of the accdent probability can help people indetify the main factors affecting the pipeline safety, and according to which people can take effective measures to reduce the acci-dent rate. Based on safety evaluation theories, mathematic model and pipeline integrity assessment methods, Evaluation of Corrosion, Third-party interfe...
