津石高速公路碳减排测算与特征规律研究

立足双碳目标发展新形势，重点聚焦绿色公路建设阶段碳排放测算研究，依托津石高速天津西段工程，通过构建碳排放测算模型，实现从多层级进行不同颗粒度的绿色公路建设碳排放量化计算，并对其排放特征进行分析，统计发现碳排放量较大的材料主要为水泥、钢类和生石灰，分别占到材料总碳排放的32.27%、41.09%和23.48%，总占比超95%；消耗量较大的材料主要为矿土料，占总消耗量比例超85%；回旋钻机及自卸汽车为排放最大的机械设备，分别占到总体排放的22.28%及19.84%，累计占比超过40%；消耗量最大的机械为电动卷扬机，消耗台班量占到总台班量的20.99%。

Research on Carbon Emission Reduction Calculation and Characteristic Law of Tianjin-Shijiazhuang Expressway

Based on the new situation of the development of dual-carbon goal, the focus is on research of the carbon emission calculation in the construction stage of green roads. Relying on the Tianjin West Section Project of Tianjin - Shijiazhuang Expressway, the carbon emission calculation model is built to achieve the quantitative calculation of carbon emissions in the construction of green road with the different granularities from the multiple levels, and the emission characteristics are analyzed. The statistics shows that the materials with the greater carbon emission are the cement, steel and quicklime, which are accounted for 32.27%, 41.09% and 23.48% of the total carbon emissions of the materials. The total proportion is over 95%. The material with the greater consumption is mainly mineral soil, which is accounted over 85% of the total consumption. The Rotary drilling RIGS and dump trucks are the largest emitting mechanical equipment, which are accounted for 22.28% and 19.84% of the total emission, and accumulatively over 40%. The machine with the largest consumption is electric hoist. The number of consuming stations is accounted for 20.99% of the total number of stations.
