道路基础设施生命周期碳排放量化分析 张怡然 (上海市城市建设设计研究总院(集园)有限公司,上海200125) 本文提出以道路基础设施为主体的碳排放分析框架,将碳排放划分为基础 设施的直接排放与间接排放,并提出生命周期各阶段的碳排放计算方法。以G321 国道的一段路面为案例,设计了三种生命周期情境:自然衰退情境、普通养护情境 和预防性养护情境,对路面生命周期碳排放量进行了计算与对比分析,为道路建设 与养护方案决策提供节能减排方面的理论支撑。 关镳词:道路基础设施,生命周期评价,碳排放,情境分析 中图分类号:U238 Quantitative Analysis of road Infrastructure Life Cycle Carbon Emissions Zhang yiran (Shanghai Urban Construction Design Research Institute( Group)Co, Ltd Shanghai, 200125 Abstract: This paper proposes a carbon emission analysis framework based on road infrastructure. which divides carbon emissions into direct and indirect emissions of infrastructure, and proposes carbon emission calculation methods at various stages of the life cycle. Taking the road surface of G321 national road as a case for case analysis, three life cycle scenarios were designed: natural recession situation, general maintenance situation and preventive maintenance situation. The calculation and comparative analysis of road life cycle carbon emissions in three scenarios were carried out to provide theoretical support for energy conservation and emission reduction in road construction and maintenance program key words: road infrastructure, life cycle assessment; carbon emission; situation analysis 引言 在日益严峻的能源短缺、环境恶化及气候变化等形势下,“低碳发展”成为全球发展的 新目标。道路运输作为交通行业能源消耗比重最大的领域,承担着节能减排的重任。从基础 设施的角度来思考节能减排路径已成为新的发展趋势,基础设施本身具有减排潜力,更重要 的是,基础设施的结构和技术状况能够影响需求侧的排放。 (c)1994-2019ChinaAcademicJournalElectronicpUblishingHouse.Allrightsreservedhttp://www.cnki.net道路基础设施生命周期碳排放量化分析 张怡然 （上海市城市建设设计研究总院（集团）有限公司，上海 200125） 摘 要： 本文提出以道路基础设施为主体的碳排放分析框架，将碳排放划分为基础 设施的直接排放与间接排放，并提出生命周期各阶段的碳排放计算方法。以 G321 国道的一段路面为案例,设计了三种生命周期情境：自然衰退情境、普通养护情境 和预防性养护情境，对路面生命周期碳排放量进行了计算与对比分析，为道路建设 与养护方案决策提供节能减排方面的理论支撑。 关键词： 道路基础设施，生命周期评价，碳排放，情境分析 中图分类号：U238 Quantitative Analysis of Road Infrastructure Life Cycle Carbon Emissions Zhang Yiran (Shanghai Urban Construction Design Research Institute (Group) Co., Ltd.
