【摘要】：随着我国高速公路建设事业的大力发展推动国民经济发展的同时，高速公路的建设对所经地域环境产生了负面影响，例如大量的填挖土石工程破坏了原始地貌和植被、施工产生的废气、废水污染物等，严重破坏了高速公路的生态环境，也影响了交通运输事业的可持续发展进程。不同的高速公路所经地域及环境特征不相同，生态环保工作的核心也不相同。由于受寒冷地区特殊的气候、水文、地质等因素影响，需要探索适合环境的生态环保技术，使高速公路建设能更好地保护沿线的生态环境。分析国内外的生态环保技术研究成果，针对我国高速公路建设的现状，结合依托工程的建设实际，采用实地勘察调研、试验分析等方法，展开寒冷地区生态环保关键技术的研究。首先分析了寒冷地区的生态环境特征，论述了公路建设对寒冷地区生态环境的影响及寒冷地区特殊条件下公路环保的主要难点，，提出了寒冷区高速公路生态环保的主要关键技术；针对寒冷地区某高速公路劣质边坡路段，论证并提出了寒冷地区岩石边坡植被袋网格化防护技术方案，对适生植物进行调查、筛选及引种，提出了劣质边坡的适生植物物种及配置模式，并对岩石边坡进行生态恢复；针对寒冷地区某高速公路服务区的建设实际，提出了服务区复合式生态土壤污水处理技术，地源热泵系统供暖技术及太阳能供电系统，有效的利用资源节约能源，建设生态节能环保服务区。课题研究丰富了寒冷地区高速公路生态环保的建设经验，为解决寒区公路生态环保关键技术问题，促进寒区交通运输事业可持续发展具有重要的理论和实践意义。
[Abstract]:With the rapid development of highway construction in China, the construction of expressway has a negative impact on the regional environment while promoting the development of the national economy. For example, a large number of earthfill excavation projects destroyed the original landforms and vegetation, waste gas from construction, waste water pollutants and so on, seriously damaged the ecological environment of highway. It also affects the sustainable development process of transportation. Different freeways have different geographical and environmental characteristics, and the core of ecological environmental protection work is also different. Because of the special climate in cold regions, hydrology. Due to the influence of geology and other factors, it is necessary to explore the ecological environmental protection technology suitable for the environment, so that the highway construction can better protect the ecological environment along the line. This paper analyzes the research results of ecological environmental protection technology at home and abroad, in view of the present situation of highway construction in China, combining with the construction practice of relying on engineering, adopts the methods of field investigation and investigation, test and analysis and so on. The key technologies of ecological environmental protection in cold regions are studied. Firstly, the characteristics of ecological environment in cold regions are analyzed. This paper discusses the influence of highway construction on the ecological environment in cold regions and the main difficulties of highway environmental protection under special conditions in cold regions, and puts forward the main key technologies of ecological environmental protection for highways in cold regions. In view of the poor quality slope section of a highway in cold area, this paper demonstrates and puts forward the technical plan of protecting rock slope in cold area by using bag mesh, and investigates, selects and introduces suitable plants. The suitable plant species and configuration model of poor slope are put forward, and ecological restoration of rock slope is carried out. In view of the construction practice of a freeway service area in cold area, this paper puts forward the compound ecological soil sewage treatment technology, the heating technology of ground source heat pump system and the solar power supply system in the service area. Effective use of resources and energy conservation, the construction of ecological energy conservation and environmental protection service area. The research enriches the experience of ecological environmental protection of freeway in cold area, and solves the key technical problems of ecological environmental protection of highway in cold area. It is of great theoretical and practical significance to promote the sustainable development of transportation in cold regions.
