摘　　要：堆石混凝土技术环境友好,经济性好,已在工程中快速推广应用。本文提出堆石混凝土碳减排效益评价模型,以中山长坑三级堆石混凝土坝工程为案例,系统分析了堆石混凝土技术的碳减排和生态成本效益。研究结果显示:相比于常规混凝土,堆石混凝土技术可以降低约55%的碳排放量;如果循环利用旧坝废弃浆砌石材料,还可进一步减少约10%的碳排放量,产生的成本效益约占总投资的23.7%。As a new type of dam building technology,Rock-Filled Concrete(RFC)can recycle demolition rock,which is environmentally friendly and economical,and has been rapidly popularized and applied in engineering projects.Under the goals of carbon peaking and carbon neutrality,this paper proposed an evaluation model for carbon emission reduction benefits of RFC to systematically describe the carbon emission reduction and ecological cost benefits of this technology.The Changkeng-ⅢProject was taken as a case to carry out the analysis.The results showed that compared with conventional concrete,RFC technology can reduce carbon emissions by about 55%,and the costeffectiveness generated account for about 23.7%of the total investment.
