Abstract：Based on the life cycle assessment(LCA)methodology,this study employed three evaluation systems to analyze the impact of key mix design parameters on the carbon emissions of precast piles and explored the applicability of a load capacity-based carbon emission evaluation approach.The research results indicate that using unit load capacity as the functional unit for evaluation can effectively reveal the intrinsic relationship between carbon emissions and key mix design parameters.Under the same load capacity conditions,the use of high-strength concrete can significantly reduce the carbon emissions of a single precast pile.In building pile foundation engineering,the application of high-strength concrete precast piles can reduce the number of precast piles required,thereby substantially lowering the overall carbon emissions of the project.
