The Typical Design Technique And Application Research Of Ecological Highway Construction In Zhejiang Province

Highway ecological system refers to the man according to his will and building service to transport a special artificial ecosystem, by road users (company personnel, vehicles), structure and environment of expressway. For the ecological highway construction, the idea is the soul, and the design is the core, and the construction is the key, and the management is the guarantee. Thereinto, the engineering design accounts for a relatively less proportion for construction fund and spent time in the whole project construction, which not only affects the relevant investment, construction period, quality and so on, but also plays an important role in the whole project construction conceptCombining the design plan of 104 national highway Deqing period reconstruction project taking "the beautiful highway" and "the ecological highway" as construction concepts, this paper introduces unique technique requirements of the ecological highway design:based on different but harmonious design professions, the ecological design concept should be adopted in the choice of line positions, the combination of bridges and road tunnels, the comparison and selection of protection forms, the design of pavement structures, the selection of pavement materials, the excavation and protection mode of holes and tunnels as well as the selection of green landscapes alongside, which takes the coordination, the protection and the greening as the purpose, the leading and the auxiliary means respectively for the better ecological highway construction.Finally, this paper introduces typical demonstration projects of the ecological traffic design for recent years-Huzhou-Jiaxing-Shanghai channel construction project (Huzhou period) and Quzhou-Nanping highway engineering (Zhejiang period), which shows the application and effect of the design concept in concrete projects...
