Abstract：To address the issue of poor stability of the foundation in coal mining subsidence areas,the component replacement method and the life cycle assessment(LCA)model are adopted to compare and analyze traditional concrete,prefabricated steel structure,and the'high-strength recycled steel+bamboo'combined structure.The results show that the unit area self-weight of this combined scheme is 129.860 kg/m2,which is 80.83%lighter than traditional concrete.The carbon emissions during the production and transportation stages of the building materials are 71.055 kgCO2e/m2,which are 83.56%and 56.43%lower than those of traditional concrete(432.144 kgCO2e/m2)and steel structure(163.080 kgCO2e/m2),respectively.The structure has both the advantages of carbon reduction and lightweighting,providing a technical path for low-carbon construction in sensitive ground areas.
