| 中文摘要: |
| 在“双碳”战略推进各行业高质量发展的重要时期,公路建设过程中的碳排放量不容忽视,围绕公路路基建设过程中碳排放量的不同阶段计算模型,对项目中的碳排放量占比进行分析。结果表明,路基建设过程中原材料水泥和砂石集料生产耗能产出是碳排放量的主要影响因素,材料运输
距离对碳排放量的影响也不容忽视,其中原材料生产碳排放量占总排放量的88.24%,材料运输过程(运输平均距离按1 km 计) 碳排放量占比8.51%,施工过程碳排放量占比3.25%。针对降低原材料生产和运输过程中碳排放量,提出控制运距、改良生产工艺和采用新能源设备等建议。 |

| In the important period of promoting high-quality development in various industries through
the “dual carbon” initiative, the carbon emissions in the process of highway construction cannot be ignored.
Based on the calculation models of carbon emissions in different stages of highway subgrade construction,
the proportion of carbon emissions in the project was analyzed. The results showed that the energy
consumption and output of raw materials such as cement and sand and gravel were the main influencing
factors of carbon emissions, and the influence of transportation distance of materials on carbon emissions
could not be ignored, with the carbon emissions from raw material production accounting for
88.24% of the total emissions, the materials transportation (an average transportation distance of 1 km)
accounting for 8.51%, and construction process accounting for 3.25%. To reduce carbon emissions in
the process of raw material production and transportation, some suggestions were put forward such as controlling
transportation distance, improving production technology and adopting new energy equipment. |
