摘要
基于全寿命周期理论和城市轨道交通系统的特点,提出了城市轨道交通全寿命周期能耗概念,将全寿命周期划分为规划设计阶段、运营装备及建材生产阶段、施工建设阶段、运营维护阶段和报废拆除及处置5个阶段,建立了5个阶段的能耗数学模型,并对北方某大城市轨道交通5号线进行定量分析,计算其全寿命周期总能耗与各个阶段能耗。计算结果表明:在全寿命周期中,上述5个阶段的能耗比重依次为0.004%、24.391%、3.884%、68.613%和3.108%,运营维护阶段能耗最大,是全寿命周期能耗控制重点,运营装备及建材生产阶段能耗次之,绿色节能材料的使用对降低能耗具有重要作用。
Based on the whole life-cycle theory and the characteristics of urban rail transit,the concept of whole life-cycle energy consumption was proposed,and the whole life-cycle of urban rail transit was divided into five stages,including plan and design stage,equipment and material production stage,construction stage,operation and maintenance stage,demolition and disposition stage.The mathematical models of energy consumption for 5 stages were set up,the energy consumption of No.5 rail transit line in a northern big city of China was quantitatively analyzed by using the mathematical models,and the total energy consumption of whole life-cycle and the energy consumption in every stage were calculated.Calculation result shows that the energy consumption proportions at the five stages are 0.004%,24.391%,3.884%,68.613%and 3.108%successively during whole life-cycle.The energy consumption of operation and maintenance stage is biggest,so the operation and maintenance stage is the key point of energy consumption control.The energy consumption of equipment and material production stage is the second biggest,the use of green energy saving materials can play an important role in reducing energy consumption.7 tabs,1 fig,23 refs.
