摘　　要：为对受地面沉降漏斗区威胁的巴基斯坦拉合尔地铁橙线高架区间MRO(维护、维修、运行)状态进行监测,研究了基于MRO状态的地铁高架区间安全模糊决策问题.提出地铁高架区间MRO状态等级,地铁高架区间MRO威胁等级,形成基于MRO状态的地铁高架区间风险等级矩阵.构建地铁高架区间MRO威胁决策模型,对拉合尔地面沉降漏斗区地铁高架区间监测设备布设方案进行优选,运用系数伸缩变换法避免模糊决策失效的可能性.研究成果为地面沉降漏斗区地铁高架区间安全研究提供了参考.To monitor the MRO(maintenance,repair,operation)status of the Orange Line elevated section of the Lahore Metro in Pakistan,which is threatened by ground subsidence funnel zone,a fuzzy decision-making problem for the safety of the elevated section of the subway based on the MRO status was studied.The MRO status level and MRO threat level for subway elevated sections,and form a risk level matrix for subway elevated sections based on MRO status were proposed.A MRO threat decision-making model for the elevated section of the subway was constructed to chose the optimization of moni-toring equipment layout in the Lahore ground settlement funnel area of the elevated section of the sub-way,and the coefficient expansion transformation method to avoid possible failure of fuzzy decision-making was used.The research results provide a reference for the safety research of subway elevated sections in the ground subsidence funnel area.
