| Local standards are good complement to national standards and industry standards, the standards guiding role in order to meet the unique geography, climate, resources and adapt the characteristics of this region generated.Local standards for the promotion of economic, social and technological developments in the region have important roles.First of all, based on the analysis of highway engineering technical standard and standard system under all kinds of standards and related data, on the basis of field investigation, expert discussions and combined Hebei geography, climate, resources and other characteristics, divided into eight categories, basic survey class, route design class, pavement type, class roadbed, bridges, tunnels class, traffic engineering, traffic safety classes, environmental category, formulated the <highway engineering standard adaptability analysis questionnairein Hebei >.Secondly, Respectivelyanalyze to Hebei existing local standards, other provinces existing local standards and relevant research results in Hebei, understanding deficiencies in the existing situation.And analyze the adaption of other provinces existing local standards and relevant research results in Hebei,Brainstorming and absorbing,in accord with the characteristics of hebei province can refer to referenceAgain, the questionnaire survey data statistics, and the use of SPSS statistical software for data reliability, validity analysis, in order to ensure the stability and reliability of the questionnaire.And put forwardthe time series of standard system in Hebei Province, with an improved TOPSIS method- TOPSIS method based on gray correlation of 65 questions to sort and classify. In order to avoid subjective factors classification divisionexits. To determine the 65 question time series.Using bayes discriminant problem further and further,Finally, Formed a highway engineering standards framework that absorbing oher advantages,refine,sublimation and having hebei characteristics.It contains the hebei province existing local standards and not standardized technical guide, the other provinces existing local standards that can be used for hebei province, The questionnaire involved the eight class 65 questions,Hebei existing research results and expert discussion on issues that not covered in the questionnaire and open framework part that.for new technologies, new materials, new technology added to. |
