摘要:
［目的］ 构建基于综合检测车的城市轨道交通轨道结构健康状态评价指标体系，实现对城市轨道交通轨道结构健康状态的科学评价，以期为轨道结构维护和管理提供科学依据。 ［方法］ 基于综合检测车检测能力，开展针对轨道结构健康状态影响因素的文献、标准规范和现场调研；遵循科学性、完备性、可操作性、层次性及可更新性等原则，初步形成包含6个一级和40个二级评价指标的城市轨道交通轨道结构健康状态评价指标体系；通过问卷调查对初步形成的评价指标体系进行调整优化，最终确立基于综合检测车的轨道结构健康状态评价体系。 ［结果及结论］ 所构建的轨道结构健康状态评价指标体系，有效融合既有学术成果、标准规范和行业共识、专家智慧，可为城市轨道交通轨道结构健康状态的评价提供技术支持，为轨道结构的维护管理提供决策依据。
Abstracts:
［Objective］ It is aimed to construct an evaluation index system for urban rail transit （URT） track structure health status based on comprehensive inspection vehicles， carrying out scientific evaluation of urban rail transit track structure health status， thereby providing a scientific basis for track structure maintenance and management. ［Method］ Leveraging the detection capabilities of urban rail comprehensive inspection vehicles， literature reviews， standard and specific analyses， and field investigations are conducted to identify the influencing factors of track structure health status. Following the scientificity， completeness， operability， hierarchy， and updatability principles， a preliminary evaluation index system for URT track structure health status is developed， consisting of 6 primary indicators and 40 secondary indicators. Based on this， a questionnaire survey is used to adjust and optimize the preliminary system， ultimately establishing a finalized evaluation index system for track structure health status based on urban rail comprehensive inspection vehicles. ［Result Conclusion］ The constructed rail structure health status evaluation index system integrates existing academic research results， established standards and specifications， industry consensus and expert insights. It provides technical support for evaluating the health status of URT track structures and serves as a decision-making basis for their maintenance and management.
