摘　　要：采用全生命周期理论,建立铁路隧道工程物化阶段和运营维护阶段碳排放核算模型。对隧道全生命周期进行数据收集和清单整理,实现碳排放量核算。对铁路隧道施工中的钻爆法和盾构法进行生命周期碳排放强度比较,结果表明钻爆法施工碳排放强度为16 785 tCO_(2e)/km,盾构法施工碳排放强度为9 184 tCO_(2e)/km,为钻爆法施工的54.7%。进一步分析表明盾构法施工水泥、钢材等材料用量及化石能源消耗量远低于钻爆法施工,直接碳排放量和其他间接隐含碳排放较少。研究对降低铁路隧道工程碳排放、推动铁路行业低碳发展具有重要参考价值。Using the full lifecycle theory,a carbon emission accounting model for the materialization and operation and maintenance stages of railway tunnel engineering is established.By collecting data and organizing inventory throughout the entire lifecycle of tunnels,carbon emission accounting can be achieved.A comparison was made between the carbon emission intensity of shield tunneling method and drilling and blasting method.The results showed that the carbon emission intensity of the life cycle of drilling and blasting method construction is 16785 tCO_(2e)/km,and that of the shield tunneling method construction is 9184 tCO_(2e)/km,which is only 54.7%of the drilling and blasting method construction.Further analysis shows that the amount of cement,steel and other materials used in shield tunneling construction,as well as the consumption of fossil energy,are much lower than those used in drilling and blasting construction.Direct carbon emissions and other indirect implicit carbon emissions are relatively low.This study has important reference value for reducing carbon emissions from railway tunnel engineering and promoting low-carbon development.
