摘要
基于工程建设碳排放量评价的基本概念和理论框架,从原材料物化、运输和施工等阶段进行桥梁改扩建能耗-原材料碳排放效益研究,并对其节能减排进行量化分析计算,以此探究节能减排新材料的应用前景。最后,运用此方法对京石改扩建工程中的沙河特大桥工程的原材料物化、运输和施工阶段的碳排放量进行分析与评价,结果表明:主要的碳排放量来自原料物化阶段而非桥梁施工过程;高性能混凝土可以作为低碳原材料替代传统普通混凝土,既能满足工程质量需求,又能产生很好的经济效果。
Based on the basic concepts and theoretical framework of the evaluation of carbon emissions by project construction, through the materialization, transportation and construction of raw materials, the arti- cle studies the benefit for carbon emission of energy consumption-raw materials in bridge reconstruction and expansion, and makes the quantitative analysis of energy conservation and emissions reduction, in or- der to explore the application prospect of new materials for energy conservation and emissions reduction. Finally, using this method, it analyzes and evaluates the carbon emission in the materialization, transporta- tion and construction of raw materials in the bridge projects of Shi-An reconstruction project. The results show that the main carbon emissions are from materialization of raw materials rather than a bridge con- struction process; high performance concrete can replace traditional ordinary concrete as low carbon raw materials, which can not only meet the demand of engineering quality, but also can produce good econom- ic effect.
