摘要
铁路选线方案设计对于铁路能否充分发挥减碳能力具有显著影响。为了评估铁路选线方案的减碳能力,分析了铁路全生命周期减碳效益影响因素,提出了相应的减碳效益估算方法,并结合实例进行了应用分析,研究结果表明:(1)某城际铁路研究地段全生命周期碳排放量为21.42×10^(8)kg,而间接减碳量为79.58×10^(8)kg,减碳效益达到58.16×10^(8)kg;(2)本文提出的铁路全生命周期减碳效益估算方法可有效评估选线设计方案带来的减碳效益。
The design of railway route selection schemes has a significant impact on whether the railway can fully exert its carbon reduction capabilities.To assess the carbon reduction capability of railway route selection schemes,an analysis was conducted from the perspective of the full life cycle to identify the factors impacting the carbon reduction benefits of the railway’s full life cycle.A corresponding carbon reduction benefit estimation method was proposed,and an application analysis combined with case studies was performed.The results show that:(1)The full life cycle carbon emissions of a certain intercity railway research section amount to 21.42×10^(8)kg,while the indirect carbon reduction is 79.58×10^(8)kg,resulting in a carbon reduction benefit of 58.16×10^(8)kg.(2)The proposed estimation method for the carbon reduction benefits of a railway’s full life cycle can effectively evaluate the carbon reduction benefits brought by the route design schemes.
