Study On Quality Evaluation Method Of Highway Feasibility Research

It affected project investment decision that whether feasibility research of highway was accomplished well. Expert's assessment and evaluation became formality mostly since there was no perfect valuation of project feasibility study system. Because projects evaluation was short of effective mass judging method system , highway engineering decision-making mostly dependence on the subjective factor during the earlier stage had brought about large amount of project risk. By establishing feasibility research evaluation index system of highway engineering, feasibility research mass completed could be evaluated scientifically, and problems in feasibility research working could be discovered, the problems could be corrected in time. By doing so project argumentation could be more sciencetific and rational, and economic effect analysis was especially rational, in project decision-making a basis was provided. Therefore it is most important to evaluate feasibility research quality of highway for entire highway construction project. By evaluating feasibility research investment accuracy could be ensured.Starting from content feasibility research of highway, the paper analysed systematically feasibility study content and request of highway, factors affected mass. By analysing systematically feasibility study theory of highway, problems in feasibility study at present were found our. Aiming at the problems, fundamental theory frame have been built to evaluate feasibility study of high. Evaluation index of feasibility study were built up by sifting index.This article used AHP and fuzzy evaluation method to evaluate feasibility researches of highway. It used membership function decided by increment ant GAHP to caculate index weight. In order to make evaluation system of feasibility research more scientific and rational. The article put forward method and content to examine evaluation result in order to make evaluation system of feasibility research more scientific and rational.Finally, the paper explored three examples to application, feasibility researches of Xi'an-BaoJi highway, MaoBa- boundary of ShanXi and SiChuan province highway, Xi'an-TongChuan highway. It demonstrated the validity and possibility of the evaluating theories and methods.
