Application Analysis of Low-Carbon in Adjacent Deep Foundation Pit Engineering of Subway
With the"double carbon"goal proposed,the total carbon emission has become one of important indicators to evaluate the level of building construction.For a deep foundation pit project near an existing subway line in Hangzhou,a new envelope technology was selected to quantify the carbon emissions generated during the construction phase of the envelope structure,and to analyze the actual emission reduction effect and the whole life cycle theory.In this paper,the carbon emission calculation model of envelope structure is established,and carbon emis-sion factor method is used to calculate and compare the carbon emission of several envelope structures under different envelope schemes.The results show that the total carbon emission of the envelope structure used in the project is 3 920.99t,which is 17.51%less than the traditional bored pile.The reduction effect is significant.The carbon emission in the construction stage of foundation pit engineering is closely related to the type of enclosure structure,and the enclosure design should be combined with the concept of carbon reduction to choose a appropriate enclosure scheme to help our country to achieve the goal of"double carbon".
