摘　　要：为研究不同软基处治技术的碳排放水平,基于生命周期理论开展就地固化、预应力管桩、泡沫混凝土技术建设期碳排放核算研究,对碳排放贡献突出因素进行分析。研究结果表明,就地固化技术碳排放强度最小,为0.05 t·m^(-3),泡沫混凝土次之,为0.30 t·m^(-3),预应力管桩最大,为1.61 t·m^(-3)。对三种软基处治技术碳排放影响最大的因素均是材料生产碳排,占93%以上。同时,从固废利用、智能管理、能源升级、生命周期降碳角度提出软基施工降碳建议。研究结果可为中国软土地区公路建设低碳技术选用及低碳建设管理提供支撑。In order to recognize the carbon emission level of different soft foundation treatment technologies,based on the life cycle theory,carbon emission calculation of in-situ solidification,prestressed pipe piles,and foam concrete technology during construction period has been researched,and the significant contributing factors of carbon emissions has been analyzed.The research results showed that,the in-situ solidification technology has the smallest carbon emission intensity of 0.05 t·m^(-3),followed by foam concrete technology with 0.30 t·m^(-3),and prestressed pipe pile has the largest amount which was 1.61 t·m^(-3).The biggest factor affecting the carbon emissions of the three types of soft foundation treatment technologies was the carbon emissions from material production,with the proportion over 93%.Meanwhile,suggestions for carbon reduction in soft foundation construction were proposed on the aspects of solid waste utilization,smart management,energy upgrading,and life cycle carbon reduction.The research results could assist low-carbon technologies selection and support the low-carbon construction and management strategy making for highway engineering in areas with soft soil foundation in China.
