Planning And Design Research Of The Protection Of Highway Ecological Environment

With the development of economy,highway is increasingly constructed. The environment problems of highway construction are gradually to be paid attention to by people, settling environment problems is the urgent affairs to highway construction. Firstly, according to the correlation of highway and environment, this article analyzes the characteristic of environment impact of highway .on the base of the sustainable development and ecology, this article defines the concept and characteristics of the ecological road, propose the process and frame in ecological highway design. With the goal of the ecological highway design, discussed the alignment Design and Compare typical program, established a Model of multiple objective decision to get a optimization design. The means of determining the weight of environment impact according to impact consequence, this means give prominence environment impact to different schemes .this method is applied to scheme decision in Zhaikete-Caishi of Ji,nan-Laiwu expressway. Besides, the article analyzes environmental compensation design, discuss highway environment design, such as sound environmental design, side slop protection design, animal passage design, planting design and so on, In order to reduce highway environment impact further.
