摘　　要：地铁在建设期需要消耗大量资源能源,排放大量温室气体。本文基于全生命周期评价理论,采用基于工程定额的清单法,建立了城市轨道交通车站建设期碳排放计算模型,以天津市典型地铁车站工程为案例,分析了车站建设期的碳排放总量和强度,分析了不同施工工法、排放范围的差异。结果表明:地铁车站建设期平均碳排放强度为4.45tCO_(2)eq./m^(2),其中,范围一、二、三排放分别占总排放3.87%、1.74%和94.39%。The construction period of subway consumes a substantial amount of resources and energy,emitting large quantities of greenhouse gases.Based on the theory of Life Cycle Assessment(LCA),this study employs the engineering quantity list method to establish a carbon emission calculation model for urban rail transit station construction periods.Using a typical subway station project in Tianjin as case study,the paper analyzes the total carbon emissions and carbon intensity during construction period of the subway station,along with comparisons among different construction methods and emission scopes.The analysis reveals that the average carbon emission intensity during the subway station construction period is 4.45 tCO_(2)eq./m^(2).In terms of emission scopes,emissions from scopes one,two,and three account for 3.87%,1.74%,and 94.39%of the total emissions,respectively.
