The Application Research On The Design Concept Of Ecological Highway In Beijing Mabei Highway

Taking the reconstruction of Mabei highway of Beijing as the engineering background, This paper mainly studied on the coordination of between ecological environment along the highway and road alignment, subgrade drainage and protection engineering, the design of soil excavating and depositing site and ecological restoration, greenery landscape design and ecological environmental impact assessment.The concrete applications of the concept of the ecological highway were studied, combined with the weather, the hydrological condition, the characteristics of topographic and geologic, vegetation types and human culture in this region.This paper analyzed the following aspects about Mabei highway:the critical technologies study on the whole harmonization between highway alignment design and ecological environment, the study on the subgrade drainage and protection engineering, the study on the ecological design of the excavating and depositing site, the study on green Landscape design and the study on ecological environmental impact assessment of Mabei highway.By the intensive analysis, this paper concluded the following innovative aspects in the ecological highway:the basic principle and design methods of road alignment in ecological highway, the design methods and typical models of the subgra. drainage in ecological highway, the critical design methods of the protection engineering, the construction points and design methods of the soil excavating and depositing site in the ecological highway, the basic principle and design methods of the greenery landscape and the main methods of the ecological environmental impact assessments of the ecological highway.
