摘要
为应对日趋严重的全球气候变暖问题,中国政府提出了“双碳”目标。交通隧道生产活动排放的温室气体是土木工程领域碳排放的主要来源之一,其节能减排工作开展的成效是按时按质完成“双碳”目标的关键。通过统计调研近10年来的相关文献,总结目前交通隧道碳排放计算分析的研究现状。结果表明,目前国内外常基于生命周期评价开展隧道生命周期的碳排放研究,同时选用排放系数法进行计算;多数文献主要围绕公路隧道、盾构隧道施工期的碳排放开展计算和减排分析,并且一般将隧道施工期碳排放划分为材料生产、材料运输和现场施工3个阶段。对隧道施工碳排放的影响因素、预测公式等方面的研究进展进行综合性叙述,可为后续研究提供参考。
In response to the increasingly serious global warming problem, the Chinese government has put forward the "carbon emission peak and carbon neutrality" goals. The greenhouse gas emitted from the production activities of traffic tunnels is one of the main sources of carbon emissions in the field of civil engineering. The efficiency of energy conservation and emission reduction is the key to achieving the "carbon emission peak and carbon neutrality" goals in time and with good quality. The current research status of carbon emission calculation and analysis of traffic tunnels is summarized through statistical research on relevant documents in the past 10 years. The results show that the carbon emission research of tunnel life cycle at present is often carried out based on life cycle evaluation at home and abroad, and the emission coefficient method is selected for calculation. Most documents mainly focus on the calculation and emission reduction analysis of carbon emissions during the construction of highway tunnels and shield tunnels, and generally the carbon emissions during the construction of tunnels are divided into three phases:material production, material transportation and on-site construction. A comprehensive description of the research progress on the influencing factors and prediction formulas of carbon emissions from tunnel construction can provide a reference for future research.
