The Sustainable Research Of The Xiyu Highway Construction Project

Freeway transportation is the national economy foundation and the service industry, and it is not only the important base to reasonable allocation of resources, improve the quality and efficiency of economic operation but also the link of the world.The rapid develoPment of the highway has played an important role and has effeetively promoted the economicdevelopment and soeial progress in our country to improve the overall technological levelof the road network to optimize the transport strueture,and to alleviate traffic"bottleneeks".But,we should also realized that the rapidly development of highway transportation especially the increase of highway caused a series questions,Such as the consumption of resource,the disruption of natural and humanistic landscape and the environment pollution,fundsefficiency and the construction quality problem,and the problem of coordination development to other modes transportation,etc.And the environmental resource condition in our country formed strong various restrictions to the development of highway transportation.So the way of sustainable development is the inevitable choice of our country freeway transportation especiallyhighway transportation development.After reading a large number of related reference literature,at the base of the existing theory and methods, this article from the basis of the connotation of sustainable development, Through the research and analysis of the domestic and international highway post projeet assessment actuality, Specific research highway construction of the sustainability content and evaluation index system, evaluation methods and overall design ideas; Through the analysis actual situation of the xi yu highway construction project, Combining previous research achievements and the understanding for highway construction projects of the sustainability, Through extensive research,and analyzed,identification,selection the factors of influence the highway construction projects of the sustainability, Established the index system for xiyu highway construction project of sustainability evaluation, And analyzed and evaluated each index; Using analytic hierarchy process and fuzzy comprehensive methods to empirical analysis and research the xiyu highway construction project, Determine the membership of matrix and fuzzy evaluation matrix of the xiyu highway construction project sustainability index,and conclusion the omprehensive evaluation results.
