隧道围岩低回弹早高强湿喷混凝土施工的减碳效应
Carbon Reduction Effect of Low Rebound Early High Strength Wet Shotcrete Construction of Tunnel Surrounding Rock
摘要
Abstract
To explore the differences in construction carbon emissions between traditional wet-shotcrete and low rebound early-high-strength wet-shotcrete for tunnel surrounding rocks,the Mingzi Mountain Tunnel of the Menglv Expressway in Yunnan Province was taken as the subject.Initially,the carbon emission quantification boundaries for the two types of wet-shotcrete construction were clarified,and the carbon emission sources were analyzed with the main thread of energy/resource consumption.Based on this,a carbon emission quantification index system was constructed by category.Subsequently,activity data such as material consumption and mechanical equipment energy consumption during the construction process were collected according to on-site surveys and design documents.Considering the source of raw materials for wet-shotcrete in the tunnel surrounding rock and the types of energy consumed in construction,criteria for selecting carbon emission factors were proposed.Finally,the carbon emissions of the two types of wet-shotcrete construction were quantified using the emission factor method,and their carbon reduction effects were analyzed.关键词
