摘　　要：山区铁路全生命周期的碳排放主要来源是运营期的列车能耗排放,而线路参数会对这部分碳排放产生不同影响。为在设计阶段考虑这部分碳排放,本文通过建立列车—线路纵向动力学模型,对山区铁路不同线路参数下CRH1型动车组列车牵引产生的单位能耗进行计算,并将其转化为碳排放量进行分析。计算结果表明,站间距是影响最大的因素,对单位里程碳排放产生次级影响,且该影响随站间距增大而逐渐减弱;坡度、坡长、控制速度与单位里程碳排放量呈线性正相关关系,而曲线半径的影响可忽略不计。The major source of carbon emissions during the whole life cycle of railways in mountainous areas is the energy consumption of trains during the operation phase,and the railway line parameters have different impacts on this part of carbon emissions.To consider this part of carbon emissions at the design stage,this paper establishes a train-track longitudinal dynamics model to calculate the energy consumption per unit mileage of CRH1 electric multiple units under different railway line parameters in mountainous areas,and then converts it into carbon emissions for analysis.Calculation results show that station spacing is the factor with the greatest influence,which has a secondary effect on carbon emissions per unit mileage,and this effect gradually decreases with the increase of station spacing;slope gradient,slope length,and control speed have a linear positive correlation with carbon emissions per unit mileage,while the influence of curve radius is negligible.
