摘　　要：依托南天高速工程,选取隧道作为碳排放计算实例,本文针对我国隧道方面碳排放研究较少问题,制定隧道施工阶段碳排放分析计算框架。首先将隧道全寿命周期分为三个阶段,确定相应碳排放来源并提出计算模型。其次,研究施工阶段碳排放,并通过现场获取的碳排放清单,整理相关文献确定各类碳排放因子,明确不同材料和机械对碳排放的贡献度。最后根据计算得到的结果,提供基于碳排放评价的节能减排方案。Relying on the Nantian Expressway project,a tunnel is selected as an example of carbon emission calculation.In view of the lack of research on carbon emissions in tunnels in our country,a brief analysis and calculation framework of carbon emissions in the tunnel construction stage is formulated.In construction stage,carbon emissions are divided into three sources and three corresponding calculation models are proposed.The carbon emission inventory obtained on construction site.Various types of carbon emission factors are determined by compiling related documents and regulations.Then the contribution of different materials and machinery to carbon emission is clarified.According to the calculated results,energy-saving and emission-reduction plans based on carbon emission evaluation are provided.
