Research on the Influencing Factors of Low-carbon Construction of Highway Tunnels
In order to achieve the goal of low-carbon construction of highway tunnels,the action paths and effects of the target influencing factors are quantitatively analyzed based on the structural equation model,and the key influencing factors are screened out.Through literature research,case analysis and expert interviews,a list of influencing factors for low-carbon construction of highway tunnels was constructed,and the influencing factors were divided into five dimensions according to the 4M1E theory.Then,the SEM modeling method was used to analyze potential variables,observed variables and action paths,etc.In this aspect,the quantitative evaluation results of each influencing factor are obtained,and the key influencing factors are analyzed.The results show that there are close interactions between five types of factors.The degree of impact on low-carbon construction of highway tunnels is environment(0.428),people(0.317),materials(0.3),methods(0.26),and mechanical equipment factors.(0.218).It is found that low-carbon awareness and ability,education and training intensity,energy utilization rate of mechanical equipment,energy types used by mechanical equipment,material type selection,material utilization and recycling rate,technological advancement of construction plans,low planning and design stage should be focused.Targeted control measures should be taken in terms of carbon concepts,rationality of construction organization design,completeness of the legal and regulatory system,and the strength of government regulatory measures to achieve low-carbon construction of highway tunnels.The research results can shows the key points for highway tunnel practitioners to promote low-carbon construction,clarify key management directions,and help achieve the carbon peaking and carbon neutrality goals.
