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.Keywords：Pinglu canal;comparison factors;route plans;route-selection principles;analytic hierarchy process (AHP)
