摘　　要：交通运输业作为我国第二大碳排放行业,约占我国总碳排放量的10%。铁路作为综合交通运输方式骨干,其单位运输性能的碳排放量低于其他运输方式。铁路路堑工程是铁路基础工程的重要结构形式,其建造过程能耗量较大,具有较高的减排潜力。根据全生命周期理论,将铁路路堑工程划分为建材生产、建材运输、施工建造与运营维护4个阶段,采用碳排放因子法测算铁路路堑工程全生命周期各阶段与总碳排放量。以某铁路路堑工程为例,测算结果表明:各阶段碳排放量分别为2293.56 t、111.46 t、1834.77 t和423.95 t;全生命周期总碳排放量为4663.74 t,各阶段碳排放量占全生命周期比重分别为49.18%,2.39%,39.34%和9.09%。在此基础上,提出铁路路堑工程碳排放深化研究的方向。As the second largest carbon emission industry in China,transportation accounts for about 10%of the total carbon emis‐sions in China.As the backbone of comprehensive transportation mode,the carbon emission per unit transportation performance of railway is lower than that of other transportation modes.Railway cutting project is an important structural form of railway founda‐tion project,which consumes a lot of energy during construction and has high emission reduction potential.According to the whole life cycle theory,the railway cutting project is divided into four stages:building materials production,building materials transporta‐tion,construction and operation maintenance.The carbon emission factor method is used to calculate the total carbon emission of each stage of the whole life cycle of railway cutting project.Taking a railway cutting project as an example,the calculation results show that the carbon emissions of each stage are 2293.56 t,111.46 t,1834.77 t and 423.95 t respectively;The total carbon emission in the whole life cycle is 4663.74 t,and the carbon emission in each stage accounts for 49.18%,2.39%,39.34%and 9.09%of the whole life cycle respectively.On this basis,the direction of further research on carbon emission of railway cutting project is put for‐ward.
