摘　　要：为合理量化明挖地铁车站建设期温室气体(GHG)排放强度及水平,基于LCA方法,开展明挖地铁车站建设期GHG排放评价工作,建立明挖车站建设期GHG排放核算公式,并结合实际工程数据进行GHG排放强度与水平的定量化分析。研究结果表明:案例明挖地铁车站建设期的GHG排放总量为47718.61 tCO_(2)e。其中,建材生产、运输和施工阶段分别占比88.91%、3.92%和7.12%;明挖地铁车站建设期的GHG排放强度为335.52 tCO_(2)e/100 m^(2)。研究结果可为促进城市交通运输领域的绿色低碳转型提供理论基础。To reasonably quantify the greenhouse gas(GHG)emission intensity and level of open-cut metro station construction,life cycle assessment method is adopted to conduct GHG emission assessment of open-cut metro station in the construction phase.In addition,a GHG emission calculation formula for open-cut metro station in the construction phase is established,and GHG emission intensity and level are quantitatively analyzed in case studies.The research results show that the total GHG emissions of the case open-cut metro station in the construction phase are 47718.61 tCO_(2) e.Among them,the production,transportation,and construction of building materials account for 88.91%,3.92%,and 7.12%,respectively.The GHG emission intensity in the construction phase of the open-cut metro station is 335.52 tCO_(2) e/100 m^(2).The research results can provide a theoretical basis for promoting the green and low-carbon transformation in the field of urban transport.
