摘要
针对当前运河线路方案选择依赖经验、宏观论证为主的问题,以平陆运河工程为例,提出一套基于量化分析的线路比选方法,旨在提升选线的科学性与决策效率。首先,基于技术、经济、环境三大维度构建选线综合评价指标体系,涵盖线路长度、土石方量(工程难度)、征地拆迁量(协调难度)、生态敏感区影响等具体指标,并采用层次分析法(analytic hierarchy process,AHP)确定各指标权重。其次,以分水岭段和六钦高速桥区段航道线路作为典型案例,通过定量对比分析不同方案的工程代价与综合效益。研究表明:指标体系与层次分析法可显著降低工程经济成本与环境影响,推荐方案在分水岭段和桥区段航道线路方案中综合投资优化比例达15%以上。研究方法可为类似运河工程提供标准化比选框架,推动线路设计从经验驱动向数据驱动转型。
Aiming at the current problems that the selection of canal route schemes relies on experience and macroscopic demonstrations,this study takes the Pinglu Canal Project as an example and proposes a set of route comparison and selection methods based on quantitative analysis,aiming to enhance the scientificity of route selection and decision-making efficiency.Firstly,a comprehensive evaluation index system for route selection is constructed based on three major dimensions:technology,economy,and environment.It covers specific indicators such as route length,earthwork volume(engineering difficulty),quantity of land acquisition and demolition(coordination difficulty),and the impact on ecologically sensitive areas.The analytic hierarchy process(AHP)is used to determine the weights of each indicator.Secondly,taking the water divide section and the section of the Liuqin Expressway Bridge area of the waterway route as typical cases,the engineering costs and comprehensive benefits of different schemes are quantitatively compared and analyzed.The research shows that the proposed index system and the Analytic Hierarchy Process can significantly reduce the engineering economic cost and environmental impact.The comprehensive investment optimization ratio of the recommended scheme is more than 15%in the waterway route schemes of the water divide section and the bridge section area.The research method can provide a standardized comparison and selection framework for similar canal projects,and promote the transformation of route design from experience-driven to data-driven.
