【 摘 要 】

In order to quantify the life cycle energy consumption of highways, life cycle assessment method is adopted to quantitatively analyze the energy consumption of a bridge-based expressway in South China. The total life cycle energy consumption was 1343967 tce, while the energy consumption per functional unit was 18733.86 tce/km. In addition, the proportion of the life cycle energy consumption for raw material production, construction and transportation was 71.90%, 13.64% and 14.47%, respectively. As data analysis shown, cement and steel bars have the greatest impact on energy consumption, the energy-saving measures during the construction phase should focus mainly on electricity and diesel, while during the operation phase should focus on controlling the power consumption. Based on the results, a series of energy-saving measures are proposed from the perspective of material-saving, energy-saving and management-strengthen.
