摘要:
[目的]目前,已投运城市轨道交通线路维保施工的安全性评价研究相对较少。为减少城市轨道交通线路运营的安全风险,应对城市轨道交通线路维保施工的安全水平进行综合评估,以指导运营生产及管理。[方法]以上海轨道交通线网内4条线路的19个维护工区为研究对象,建立了具有4层架构的城市轨道交通线路维保施工安全效能评价指标体系。基于线路维保施工指标的实际情况,对熵权法进行了改进,并与突变级数理论相结合,提出了基于改进熵权-突变级数的线性组合评价方法。采用此评价方法对19个维护工区的维保施工安全效能进行评价分析。[结果及结论]基于改进熵权-突变级数的线性组合评价法通过了一致性检验,其评价结果稳定、可靠。该方法有效扩大了熵权法与突变级数理论在城市轨道交通维保施工评价中的适用性,实现了城市轨道交通线路维保施工领域的动态综合评价。

[Objective] At present, there are relatively few studies on the safety assessment of maintenance and construction of urban rail transit operation lines. In order to reduce the operation safety risk of urban rail transit lines, the safety level of urban rail transit line maintenance construction should be comprehensively evaluated to guide the operation production and management. [Method] Targeting the 19 maintenance work areas on 4 lines in Shanghai rail transit network, a 4 hierarchy-structured safety effectiveness evaluation index system for urban rail transit line maintenance and construction is established. Based on the actual situation of line maintenance construction indexes, the entropy weight method is improved and combined with the mutation progression theory, and a linear combination evaluation method based on improved entropy weight and mutation progression is proposed as the result. The safety effectiveness of maintenance construction in 19 mainten-ance work areas is evaluated and analyzed with this method. [Result & Conclusion] The linear combination evaluation method based on improved entropy weight-mutation level passes the consistency test, and the evaluation results are stable and reliable. This method effectively expands the applicability of entropy weight method and mutation level theory in the evaluation of urban rail transit maintenance construction, and realizes the dynamic comprehensive evaluation in the field of rail transit line maintenance construction.
