In order to achieve the goal of "double carbon" in China, to provide data support for energy saving and emission reduction of foundation pit projects, to solve the problem of complicated and tedious process of quantifying greenhouse gases in foundation pit projects, to improve the engineering quality of foundation pit projects, and to increase carbon emission as one of the evaluation indexes of foundation pit projects, this paper establishes a modular calculation method of embodied carbon emission for foundation pit projects based on the whole life cycle theory. Based on the whole life cycle theory, this paper establishes a modular calculation method for the embodied carbon emission of foundation pit projects, considers the characteristics of "temporary" foundation pit projects, defines that the embodied carbon emission of foundation pit projects includes carbon dioxide generated in the building materials production stage, construction stage and transportation stage, and calculates the carbon dioxide emissions of two open-cut underground stations and one open-cut interval of the western section of Beijing Railway Line 11 (Winter Olympic Branch Line). Carbon dioxide emissions were calculated for three foundation pit projects in the western section of Beijing Railway Line 11 (Winter Olympic Branch), and the embodied carbon emissions of foundation pits were analyzed from three levels: element level, module level and phase level. Considering the influencing factors of excavated earth volume, backfilled earth volume and number of bored piles, the main influencing factors of embodied carbon emissions of foundation pit projects were analyzed.
