基于灰色系统理论的大型枢纽铺架基地规划技术研究

铺架基地承担着铁路铺轨施工及其物料存放、供应任务，其规划、选址与设计是影响铁路铺轨工程后续工程的安排、施工质量与总工期的关键。目前针对铺架基地选址及布置方面的研究尚停留于定性分析研究阶段，缺乏科学的、定量化的选址及布置方法。依托重庆西站改造工程，创新性地将灰色系统理论应用于山区高速铁路铺架基地的设计与施工中，分别利用灰色模糊综合评判方法以及多目标加权灰靶决策方法，提出了铺架基地选址与规划方法，该方法可以为今后类似山区地形预制梁场和铺轨基地等大型临时建设工程提供参考借鉴。

Research on Planning Technology of Large Pivot Laying Base Based on Grey System Theory

The track laying base mainly undertakes the tasks of road material storage and supply in the construction of railway track laying and beam erection project. Its planning, site selection and design not only affect the efficiency of transporting materials, but also directly affect the arrangement of subsequent projects, construction quality and total construction period. At present, the research on the site selection and plane layout of laying base is still lagging behind, and still stays in the stage of qualitative analysis and research, lacks systematic research and advanced research results. Relying on the reconstruction project of Chongqing West Railway Station, creatively applies the grey system theory to the integrated site selection planning and plane layout of large-scale hub laying base of high-speed railway in mountainous areas, and analyzes and summarizes the construction process optimization scheme adopted in the construction of laying base. The research can provide reference for large-scale temporary construction projects such as precast beam yard and track laying base in similar mountainous terrain in the future.
