为解决现有技术中人工现场临时搭拆脚手架耗时费力、成本高、效率低的问题，采用AHP（analytic hierarchy process）-TRIZ多理论集合方法，开展铁路运营隧道病害治理台车方案设计。基于层次分析法（AHP），梳理铁路运营隧道病害治理台车的设计要素，并对各设计要素的权重进行计算和排序，得出各设计要素权重由大到小排序为强度和刚度大>防溜车和应急回收>快速展开与收缩>防护栏>钢拱架机械化安装>快速进场和退场=非工作状态尺寸小>全断面作业平台>障碍物识别>自适应展开。根据权重大小排序，结合病害治理施工边界条件，确定防护栏、防溜车和应急回收、强度和刚度大、快速进场和退场、非工作状态尺寸小、快速展开与收缩、全断面作业平台、钢拱架机械化安装8个设计要素。依据AHP 评价结果，将设计要素两两对比，构建设计要素间的矛盾矩阵，对设计要素之间存在的物理矛盾和技术矛盾进行描述，借助TRIZ理论，明确解决上述矛盾的原理，进而设计台车方案，并基于台车方案研制设备样机。研究表明： 1）采用AHP法和TRIZ理论，能够对收集到的功能需求进行相对客观的分析，并能找到解决设计要素之间矛盾的方案； 2）基于AHP-TRIZ理论设计的铁路运营隧道病害治理台车具有较好的断面适应性。

Existing technologies for scaffold construction in operational railway tunnels present multiple disadvantages, including time consumption, high cost, and low construction efficiency. To address these issues, the analytic hierarchy process(AHP)TRIZ multitheory set method has been utilized to develop a disease treatment trolley scheme. Utilizing AHP, the critical design elements of the trolley are identified, and their weights are calculated and ranked as follows: B3>B2 > C3 > B1 > D2 > C1 = C2 > D1 > D4 > D3. Based on this ranking and the boundary conditions for disease control construction, eight design elements are prioritized: protective barriers, equipment antislip and emergency recovery, high strength and stiffness, rapid entry and exit, compact nonworking size, quick expansion and contraction, fullsection operational platform, and mechanized installation of steel arch frames. Through pairwise comparison of design elements and construction of a contradiction matrix, physical and technical contradictions are identified and addressed using TRIZ theory, which clarifies the principles for resolving these contradictions. Subsequently, a trolley scheme is designed, and a prototype is developed. These findings indicate that the AHPTRIZ method provides an objective analysis of functional requirements and effectively resolves conflicts between design elements, leading to a trolley that exhibits excellent crosssectional adaptability.
