As a large-scale embankment structure，the quantitative calculation of the carbon emission of twisted-king block is of great significance for energy saving.Based on the LCA theory，this paper divides the materialization stage of twisted-king block into five stages，material production，material transportation，component manufacture，component transportation and site construction.The carbon emission measurement model is constructed to calculate the carbon emission in the materialization stage.Taking a large embankment as an example，the steps of measuring carbon emission is demonstrated.The results show that the carbon emissions during the materialization stage mainly come from the materials production and transportation.By comparing the carbon emissions of different transportation distances and patterns of sand and gravel，it is concluded that the carbon emissions can be effectively reduced by using nearby materials or waterway and railway transportation for long distance transportation.By comparing the carbon emissions of different fuel vehicles，the carbon emissions of gasoline vehicles and LNG vehicles are lower than that of diesel vehicles.
