摘　　要：为助力我国桥梁工程实现低碳发展,对桥梁工程碳排量计算和低碳性能评价进展进行归纳总结。桥梁工程碳排量计算研究主要包括单独桥梁的碳排量计算和不同桥梁的碳排量对比2个方面,在单独桥梁的碳排量计算方面,采用排放因子法计算桥梁碳排量,桥梁碳排量主要来自建材生产和运维阶段,建材生产阶段碳排量主要来自混凝土和钢材;在不同桥梁的碳排量对比方面,明确了桥梁材料、结构形式等关键参数对桥梁全寿命周期碳排量的影响。桥梁低碳性能评价体系研究主要包括低碳性能评价方法和桥梁综合评价体系2个方面,在低碳性能评价方法方面,提出了多种基于权重体系的低碳性能评级和评分方法;在桥梁综合评价体系方面,初步建立了桥梁低碳性能与经济性、可靠性等其它性能指标的联系。针对4个方面的研究不足,应开展更多桥梁排放因子数据库和桥梁建造方式对碳排量影响的研究;应采用基于大数据的低碳性能评价方法,以避免权重体系带来的主观偏差;桥梁综合评价体系应将碳排放指标、环境成本、全寿命周期成本等考虑到桥梁方案设计和教育理念中,这也应作为桥梁工程碳排放研究的最终目标。To bolster China′s bridge engineering in realizing low-carbon development,the research progress of carbon emission calculation and low-carbon performance evaluation of bridge engineering is studied.The research on carbon emission calculation of bridge engineering mainly involves two categories:the calculation of carbon emission of a specific bridge and the comparison of carbon emissions of different bridges.For the calculation of carbon emission of a specific bridge,the emission factor method is generally used to calculate the carbon emission of bridges.The carbon emissions of bridges mainly come from the material production,operation,and maintenance.The carbon emissions during the material production stage mainly come from concrete and steel.For the comparison of carbon emissions of different bridges,the influence of critical parameters,such as material type and structural form,on the life-cycle carbon emissions of bridges is clarified.The research on low-carbon performance evaluation of bridge engineering mainly includes two categories:the evaluation method of low-carbon performance and the comprehensive evaluation system of bridges.For the evaluation method of low-carbon performance,various low-carbon performance rating and scoring methods based on the weight system are proposed.For the comprehensive evaluation system of bridges,the relationship between the low-carbon performance and other performances,such as economy and reliability,is preliminarily established.Suggestions and prospects are put forward for the insufficiencies in these four categories of research in the following aspects:the bridge emission factor database and the impact of construction methods on bridge life-cycle carbon emissions need to be further studied;the bridge low-carbon performance evaluation method based on big data should be adopted to avoid subjective bias caused by the weight system;the bridge comprehensive evaluation system should take the concepts of carbon emission index,environmental cost,and life-cycle cost into considerat
