【摘要】：我国公路事业的快速发展导致能源大量消耗和环境迅速恶化。随着全球可持续发展观念的推广,人们越来越关注公路建设过程中的能源消耗和环境影响,全球各国政府、研究机构及企业等组织都开展了大量的绿色低碳研究和实践。其中生命周期评价(LCA)方法,能够量化分析道路建设各环节、各阶段的能源消耗及环境评价,为道路工程的绿色化、低碳化建设提供指导,意义重大。本文对路面工程中运用LCA的基本理论和方法进行了全面分析。从LCA目标与范围确定、清单分析、影响评价等三个主要方面概括分析国内外主要研究现状,分析认为目前路面LCA研究存在以下问题:范围界定没有统一标准;国内缺少数据支撑无法形成标准数据库;关于数据质量的分析研究较少;影响评价不全面等缺点。针对其上述问题,文章提出了工作建议。本文以北京市某一城市道路的养护施工为例,对其产生的交通环境影响进行研究。从不同养护工程实施方案产生的交通及车辆燃油变化和施工作业本身产生的碳排放量两个方面进行分析。对于第一个方面,利用交通仿真方法对不同养护工程实施方案进行交通影响的定量评价,并对由此导致的车辆燃油的变化进行分析。根据分析结果,进行合理、科学的施工组织方案优化,并给出城市道路养护实施方案评价流程和方法;对于第二个方面,基于路面工程LCA理论,合理界定评价范围并确定评价对象。另外,在调研基础上,运用公路工程定额等相关行业标准作为基础数据库,对城市道路养护施工作业产生的碳排放量进行计算。LCA软件能够简化生命周期评价工作,快速提供环境评价依据,优化路面工程施工方案。为促进国内路面生命周期评价技术开发,本文以路面LCA软件Athena为例,通过实际案例分析详细阐述LCA软件的基础理论及应用方法。并结合国内道路的建设运营特点,提出形成适合中国国情的LCA分析模型所需经过的步骤。
[Abstract]:The rapid development of China's highway leads to rapid deterioration of the large energy consumption and the environment. With the development of the concept of global sustainable development, people pay more and more attention to energy consumption and environmental impact of highway construction in the process of global governments, research institutions and enterprises and other organizations have carried out the research and practice of green low carbon in large quantities. The life cycle evaluation (LCA) method, to all aspects of road construction and quantitative analysis, energy consumption and environmental assessment of each stage, for the green road project, to provide guidance, low-carbon construction is of great significance. This paper makes a comprehensive analysis of the basic theory and method of LCA pavement engineering. From the LCA goal and scope definition, inventory analysis of the three main aspects of impact evaluation, analyzes the status quo of domestic and foreign research and analysis that the current problems of LCA pavement: no unified defined scope Standard; the lack of domestic data support to form a standard database; about the quality of the data analysis research; impact assessment is not comprehensive. In view of the disadvantages of the above problems, the article put forward suggestions. Based on the road maintenance construction of a city in Beijing city as an example, studied the effect of traffic environment in the two aspects. Carbon emissions resulting from different maintenance project implementation plan of traffic and vehicle fuel change and construction operation itself were analyzed. For the first aspect, the quantitative evaluation of traffic impact on the party to implement different curing project by using traffic simulation method, and the resulting change of vehicle fuel were analyzed. According to the analysis of reasonable the results, scientific construction scheme optimization, and gives the city road maintenance processes and methods of implementing scheme evaluation; for the second aspects, based on the pavement LCA engineering theory, the reasonable definition of evaluation scope and determine the evaluation object. In addition, on the basis of the investigation, the use of highway project quota and other related industry standards as the basis for the database, carbon emissions of city road maintenance and construction operations of.LCA software can simplify the life cycle assessment work, to provide rapid environmental assessment based on the optimization of pavement engineering construction scheme. To promote technology development of domestic pavement life cycle assessment, based on the LCA software Athena road as an example, through the analysis of actual case in detail the basic theory and application of LCA software. The construction and operation characteristics and combining the domestic road, put forward for the formation of Chinese situation analysis model of LCA through the required steps.
