【摘要】 本文基于生命周期评价理论,根据全面性、多角度等原则将环境影响成本分为资源消耗、大气污染、水污染、噪音污染、和固体废弃物污染等成本。利用数学模型量化分析工程实例,得出材料生产、施工、运行维护、拆除及固体废物处理4个阶段的环境影响成本,结果显示材料生产阶段对环境的影响最为显著,且各类环境影成本中资源消耗带来的经济损失最为严重。本研究对于促进公路隧道经济效益与环保效益的平衡,可用于公路隧道工程的综合评价。更多还原

【Abstract】 Based on the theory of life cycle assessment,this paper divides environmental impact costs into resource consumption,air pollution,water pollution,noise pollution,and solid waste pollution according to the principles of comprehensiveness and multi-angle.The mathematical model was used to quantitatively analyze the engineering examples,and the environmental impact costs of material production,construction,operation and maintenance,demolition and solid waste treatment were obtained.The results showed that the material production stage had the most significant impact on the environment,and the environmental impact costs were all The economic loss caused by resource consumption is the most serious.This study can be used to promote the balance between economic benefits and environmental benefits of highway tunnels,and can be used for comprehensive evaluation of highway tunnel engineering.更多还原
