摘要:
为了将轨道交通土建系统设备伤损检查、沉降监测等数据纳入风险评估体系，将土建系统分为轨道、隧道、桥梁3个子结构。分析了各子结构的风险因素，确定其扣分标准，建立了基于AHP(层次分析法)熵值法的轨道交通土建系统风险评价体系。该体系根据专家意见计算出基于AHP的权重，以此作为该评价体系的主要权重值。在此基础上，对可连续监测的部分评价指标数据进行基于熵值法的权重计算。使用综合集成赋权法，将基于AHP、熵值法计算得到的权重融合，得到各评估项目和评估指标的最终权重。以某地铁线路2013年和2016年的监测数据为案例，利用该体系分别对这两个年度的土建设施进行风险评估，并提出了相应的养护建议。结果表明，该评估体系可为轨道交通土建系统的运营安全风险评估提供参考。
Abstracts:
To accommodate data of rail transit civil infrastructure equipment damage inspection and settlement monitoring into the risk assessment system, the civil infrastructure system is split into three substructures: track, tunnel and bridge. The individual risk factors of each substructure are analyzed. Deduction standards are determined, and rail transit civil infrastructure risk assessment system based on AHPentropy method is established. The system refers to professional opinions to calculate AHP weights as main weighting values. On this basis, continuous monitored data are collected to calculate entropy method weights of some assessment factors, and combination weighting method is utilized to mix both of AHP weights and entropy method weights as final evaluation index weights for each assessment item. Taking the monitored data of certain metro line in 2013 and 2016 as an example, civil systematic risk in different years is assessed and corresponding advice of maintenance is put forward. The analytical result demonstrates that the assessment system can provide reference for operation safety risk assessment for other rail transit systems.
