摘要
随着我国提出“碳达峰”和“碳中和”目标,建筑工程领域对碳排放问题的关注日益增加。将全生命周期理论和排放.因子法相结合,对绵阳市某城市综合体基坑的碳排放量进行了精确计算,得出其总排放量为2346275t。分析结果表明,建材生产阶段是碳排放的关键步骤,而地基处理和基坑支护环节对碳排放总量的影响尤为显著。因此,减排的关键在于优化建材种类选择和减少用量,以及改变基坑支护方案。对于推动基坑工程的绿色发展具有重要意义。
With China's introduction of the"carbon peak"and"carbon neutrality"objectives,concern over carbon emissions in the construction engineering sector has grown.By integrating life cycle assessment theory with the emission factor method,precise calculations were conducted on the carbon emissions from the foundation pit of an urban complex in Mianyang City,with total emissions calculated as 2,346.272 tonnes(t).Analysis indicates that the production phase of building materials is the primary contributor to carbon emissions,and foundation treatment and excavation support procedures have a particularly significant impact on the total emissions.Consequently,key mitigation strategies involve optimising material selection,reducing consumption,and modifying excavation support methodologies.This findings are of considerable significance for advancing the sustainable development of excavation engineering.
