摘要
人类活动是自然界碳循环中一个重要影响因子,其中公路交通建设占有较大比重,国家“十四五”规划也对碳排放目标进行了重点部署,因此桥梁建设中的低碳策略成了设计中的重要考量。本文首先阐述了碳足迹的分析工具与核算方法,拆解出桥梁碳排放增量与区域碳固化减量两方面分别进行计算,并结合不同设计方案综合量化,分析比较不同方案全生命周期碳足迹特性,最后总结得出相应的碳减排措施。
Human activity is an important factor in the natural carbon cycle,and highway traffic construction accounts for a large proportion among these activities.Considering that the national"Fourteenth Five Year Plan"has also focused on the deployment of carbon emission target,strategy of lower carbon emission in bridge construction has become an important consideration in bridge design.Firstly,the paper expounded the analysis tools and accounting methods of carbon footprint,which disassembled carbon footprint into bridge carbon emission increment and regional carbon solidification reduction and calculated then separately.Then the life cycle carbon footprint characteristics were compared and comprehensively quantificated combined with different design schemes.Finally,the corresponding carbon emission reduction measures were summarized.
