Abstract
The research on the evaluation and comparison for connection schemes of railway special lines,which quantitatively evaluates various connection schemes and scientifically and intuitively selects the optimal connection schemes,has an important guiding role in the decision-making for railway special line projects.By comprehensively considering technical and economic factors such as the influence on connection stations and existing line operations,project implementation difficulty,and investment costs,this paper constructed a set of evaluation criteria for railway special line connection schemes.A principal component analysis-based method for evaluating and comparing connection schemes was proposed.Using a specific railway special line project in Guangyuan City as a case study,three connection schemes were analyzed qualitatively and quantitatively in terms of their advantages and disadvantages.Based on the comprehensive evaluation values,the relatively optimal connection scheme was selected,and the quantitative analysis results were compared with the qualitative analysis conclusions to verify the consistency of the selection results,thus demonstrating the effectiveness of the proposed method.The results show that this method can effectively evaluate and compare different connection schemes,providing valuable support for decision-making in railway special line projects.关键词
