基于LCA的轮轨与磁悬浮方案比选研究

Research on the Comparison and Selection of Wheel Rail and Maglev Schemes Based on LCA

本文基于LCA对京沪高铁的轮轨与磁悬浮方案进行比选研究,在材料、设备、运输与施工阶段对轮轨与磁悬浮的能源消耗进行计算分析,最后对两者进行综合比选评价。从能源消耗的全生命周期评价角度为铁路在轮轨与磁悬浮两个方案的比选评价提供科学可靠的参考思路。

As a construction field with huge energy consumption,railway engineering needs to actively respond to the dual carbon policy and sustainable development concept,and actively choose appropriate construction plans to reduce energy consumption.This article conducts a comparative study on the wheel rail and maglev schemes of the Beijing Shanghai high-speed railway based on LCA.The energy consumption of the wheel rail and maglev is calculated and analyzed during the materials,equipment,transportation,and construction stages.Finally,a comprehensive comparative evaluation is conducted on the two.Provide scientific and reliable reference ideas for the comparison and evaluation of railway wheel rail and maglev schemes from the perspective of full lifecycle assessment of energy consumption.
