Study on Life Cycle Carbon Emissions of Seawall Armor Structure
The life cycle carbon emission of buildings accounts for 51.2% of the total carbon emission in China,and it has become a key factor in accomplishment of dual carbon goal.Taking two common seawall of Zhejiang Province as an example,the carbon emissions of seawall was researched based on the theory of whole life cycle.The armor structure car-bon emission calculation stages were set,the carbon emission coefficients of materials and equipments were determined.The carbon emission coefficients of different structures were computed,and engineering work of structures was compu-ted.And then the production and construction stage,demolition stage,operation stage,and life cycle carbon emissions were analyzed.It is shown that the life cycle carbon emissions of seawall armor structure embodies the features,such as the most sensitive to the structures made from synthetic materials,happened in production and construction stage,and the considerable influence of recovery percent and quantities of structure in operation stage.
