摘要
目前国内针对BOT模式下的市域铁路房建结构维保策略尚处于探索阶段,传统地铁维保研究成果主要是基于经验的定性分析,缺乏对各类潜在影响因素的定量分析和影响路径分析。为深入探索市域铁路房建结构维保策略对维保质量的影响机制,文章设计并实施问卷调查,并建立结构方程模型进行量化分析。研究结果显示,委外策略、委外管理水平及质保策略对维修质量具有显著的正向推动作用,且影响力依次递减。同时,业主单位在整个管理路径中对维修质量起到一定的正向调节作用。结合某BOT模式下新建市域铁路实际运营经验,进一步从委外模式、合同计价方式及质保策略等多个维度,提出相应的维保优化策略,以期为后续新线路运营筹备提供参考和借鉴。
At present,the maintenance strategy for urban region railway building structures under the BOT model in China is still in the exploratory stage.Traditional metro maintenance research results are mostly based on qualitative analysis of experience,lacking quantitative analysis and impact path analysis of various potential influencing factors.To further explore the impact mechanism of maintenance strategies on maintenance quality,this article designs and implements a questionnaire survey,and establishes a structural equation model for quantitative analysis.The research results show that outsourcing strategy,outsourcing management level and quality assurance strategy have a significant positive driving effect on maintenance quality,and their influence decreases in order.At the same time,the owner unit plays a certain positive regulatory role in the maintenance quality throughout the entire management path.Based on the actual operation experience of a newly built urban region railway under a certain BOT mode,this article further proposes corresponding maintenance optimization strategies from multiple dimensions such as outsourcing mode,contract pricing method and quality assurance strategy,providing reference and inspiration for the subsequent preparation of new line operation.
