基于结构变形的地铁安全评估分析

Analysis of Metro Safety Assessment Based on Structural Deformation

通过分析地铁结构变形的影响因素,结合评估体系中评价指标的选取原则,确定了地铁结构变形评估指标体系;利用层次-模糊数学综合评估理论建立了地铁结构变形安全性评估模型;结合工程实例,对评估结果进行数字化和科学化表达,得到地铁结构变形的安全状况和影响其状况的主要因素。这对确定运营期地铁的养护措施,提高地铁运营安全,给有关管理部门提供决策依据、采取有关措施有重要意义。

With the analysis of influencing factors of metro structural deformation, combining with the principle of selecting evaluation index about evaluation system to determine evaluation index system of metro structural deformation, then using level-fuzzy comprehensive evaluation theory, subway structural deformation safety assessment model is established. Finally, combined with engineering example, digitally and scientifically expressing assessment results, the security situation and the main factors affecting the situation of metro structural deformation is gotten, which have a great important significance to determine the conservation measures of metro operation, to improve the safety of subway operation, and to provide the relevant administrative departments with decision basis.
