城市地下综合管廊运维阶段的风险因素分析

Risk Factor Analysis on the Operation and Maintenance Phase of Urban Underground Utility Tunnels

城市综合管廊将电力、通信、燃气、供热、给排水等各种工程管线集于一体,是人地矛盾和工程技术发展到一定阶段的产物。本研究针对现阶段对综合管廊运维的风险研究程度不够的问题,分析了综合管廊运维阶段的潜在风险因素。从项目管理者的角度出发,通过收集国内外有关文献,确定了综合管廊运维阶段的20个关键影响因素,研究分析了风险因素影响因子,并建立了初步的风险指标体系。通过定量与定性研究相结合的研究方式,构建了针对综合管廊运维阶段安全风险评价的改进层次分析法-熵权法-模糊TOPSIS评价模型,结合问卷调查的方式收集数据,并确定风险因素的权重以及风险影响程度。最后将新建立的模型应用到实际工程项目中,判断综合管廊工程项目运维阶段的风险排序,并给出相应的策略与风险管理的侧重点,为类似工程运维提供参考。

The urban underground utility tunnels integrating various engineering pipelines such as electricity pipelines,communication pipelines,gas pipelines,etc.,are the product when human-land contradictions and engineering technologies develop to a certain stage.The research considered the problem that the risk research on the present operation and maintenance stage of the integrated pipeline gallery is insufficient,and analyzed the potential risk factors in the operation and maintenance stage of the integrated pipeline gallery.From the perspective of the project manager,through the collection of relevant domestic and foreign documents,20 key influencing factors in the operation and maintenance stage of the integrated pipeline gallery were determined,their influencing factors were studied and analyzed,and a preliminary risk index system was established.Through research a method combining quantitative studing with qualitative studing,an improved analytic hierarchy process-entropy method-fuzzy TOPSIS evaluation model for the safety risk evaluation of the integrated pipeline gallery operation and maintenance stage was constructed,and the data was collected through questionnaire surveys,and the risk factors,the weight and degree of risk impact were determined.Finally,the newly established model was applied to actual engineering projects to determine the safety risk level of the integrated pipeline gallery project in the operation and maintenance phase and gave corresponding strategies to provide reference for the operation and maintenance of similar projects.
