摘要
本文基于碳排放视角,选取西南地区重大干线铁路典型桥梁结构为研究对象,通过收集施工阶段清单数据,建模分析不同施工工艺桥梁结构碳排放量,筛选出碳排放贡献度累计超80%的清单数据,对比分析不同施工工艺对典型桥梁结构碳排放量的影响。本文研究丰富了西南地区高速铁路桥梁结构碳排放清单数据库,探索了建立绿色桥梁结构碳排放评价标准,为分析重大干线铁路设计、施工、运维及拆除全生命周期碳排放量,更好实现我国工程建设领域“双碳”目标打下基础。
Focusing on typical bridge structures on the trunk railways in the southwest region from the carbon emission perspective,the paper established the model of carbon emission for different construction technologies and bridge structures based on the list data collected in construction,among which the list data contributing cumulatively over 80%to carbon emission were selected,and the influence of different construction technology on carbon emission of typical bridge structure is analyzed.The results of this study enrich the database of carbon emission from high-speed railway bridge structures in the southwest region,make an exploration on the establishment of green bridge structure carbon emission evaluation standards,and lay the ground for analyzing the full lifecycle carbon emission for the design,construction,operation,and decommissioning of trunk railway,facilitating the better realization of the“double carbon”goals in China’s construction sector.
