管道地质灾害风险半定量评价方法与应用

Technique and application of geologic hazard risk semi-quantitative assessment of pipeline

基于指标评分法的管道地质灾害风险半定量评价方法通过调查评价指标的客观存在状态,根据事先确定的评分和权重计算灾害的相对风险,在满足地质灾害调查阶段风险排序、分级需求的基础上,指导风险控制规划的制定。建立了适用于输油气管道的地质灾害风险半定量评价体系和风险分级标准,开发了管道地质灾害风险管理系统软件,该软件集成了基于指标评分法的风险半定量评价技术,并集成信息管理、风险管理等技术,为管道地质灾害风险管理工作提供信息、技术平台和管理平台。应用该方法对油气管道3300余处灾害点进行统一标准的风险评价,获得了令人满意的评价结果,为管道地质灾害风险整治规划的制定提供了重要依据。

Semi-quantitative assessment technique is one of the most important support techniques for geologic hazard risk management of pipeline.With the investigating the objective existence state of evaluation index and calculating the relative hazard risk based on the grade and weight predetermined,the semi-quantitative assessment technique based on scoring index method can meet the requirements of risk sequence and classification in the stage of geologic hazard investigation and provide the basis for decision-making on mitigation planning in future.In this research,the semi-quantitative assessment technique has been established,which is available for the geologic hazard risk assessment of oil and gas transport pipeline and the standard of risk ranking.A pipeline geologic hazard risk management system has been developed,that is,the risk semi-quantitative assessment technique based on scoring index method,data management and risk management technique are integrated together.It provides information,technique and management platform to the geologic hazard risk management of pipeline.
