摘要 扭王字块作为量大面广的护堤结构,其碳排放的量化计算对于节能减排具有重要意义。基于LCA理论,将扭王字块物化阶段划分为原材料生产、原材料运输、构件制作、构件转运和现场施工5个阶段,采用碳排放系数法构建扭王字块物化阶段的碳排放测算模型,并以某大型护堤工程为例,演示计量扭王字块物化阶段碳排放的具体流程。结果表明:扭王字块物化阶段的碳排放主要来自原材料生产和运输;通过对比砂石材料不同运距和运输方式的碳排放量,得出就近取材和长距离采用铁路或水路运输可有效降低碳排放;对比公路运输不同燃料车辆的碳排放,汽油车和LNG车的碳排放低于柴油车。 As a large-scale embankment structure,the quantitative calculation of the carbon emission of twisted-king block is of great significance for energy saving.Based on the LCA theory,this paper divides the materialization stage of twisted-king block into five stages,material production,material transportation,component manufacture,component transportation and site construction.The carbon emission measurement model is constructed to calculate the carbon emission in the materialization stage.Taking a large embankment as an example,the steps of measuring carbon emission is demonstrated.The results show that the carbon emissions during the materialization stage mainly come from the materials production and transportation.By comparing the carbon emissions of different transportation distances and patterns of sand and gravel,it is concluded that the carbon emissions can be effectively reduced by using nearby materials or waterway and railway transportation for long distance transportation.By comparing the carbon emissions of different fuel vehicles,the carbon emissions of gasoline vehicles and LNG vehicles are lower than that of diesel vehicles.
