Abstract: The research on the risk management based on Web GIS is being considered to improve safety management of oil pipeline.An information management system for oil pipeline based on Web GIS has been established.According to the collected practical pipeline data and ananalytic hierarchy process(AHP),the latent risk of oil pipeline was quantified based on the modified Muhlbauer W K method,the risk grading of oil pipeline was devised and daily maintenance was emphasized.The orientation system of leakage in the oil pipeline was devised based on negative pressure,and the best emergency rescue paths was decided based on improved Dijkstra arithmetic.Finally,it was demonstrated with examples that this system of the risk management and emergency response based on Web GIS is more veracious and easier to apply.

Key words: Oil pipeline,    , Risk management,    , Emergency response,    , Rescue paths

摘要： 基于WebGIS的管理系统研究能够提升输油管道安全管理水平。采用GIS软件,构建了基于Web GIS的长距离输油管道信息管理系统;根据采集的管道沿线相关数据,基于修正的MuhlbauerW K 的风险评分法,结合层次分析法,量化管道潜在风险,设定管道风险等级,加强日常维护与管理;基于负压波原理,开发了输油管道泄漏点定位系统;结合改进的Dijkstra算法,提出了最佳应急响应救援路径确定方法。实例表明:基于WebGIS的风险管理与应急响应系统更准确、实用。
