Study On The Fuzzy Regression Application Of Potholes And Cracks Maintenance Ratio Of Henan Highway

This dissertation is a sub-part of the predication method of highway maintenance ratio and expense forecast. This result will solve the question in determining the maintenance cost of Henan highway potholes and cracks, and it will instruct the control of highway maintenance funds, and has vital practical significance and application value. The dissertation research content is as follows:1. Analyzed the early time damage reason of highway asphalt pavement, through the literature investigation and study, the service quantity data investigation and the scene observation, initially determined the direct influence factor of highway pavement amazement.2. Carries on the single factor analysis to the investigation data, pointed out the resilience influence relations to the highway maintenance service, determined two primary single factors - that is, the road age and the volume of traffic.3. Analyzing the statistical data, and studies the multi-dimensional fuzzy regression analysis forecast theoretical model.4. Referencing the variable changing tendency, revises the primary data, constructs the modeling data sheet. Substitutes into the fuzzy regression model, obtains the fuzzy regression coefficient.5. Carries on the appraisal to the result, contrasts the forecast value and the actual statistical value, and its growth tendency, as well as the forecast value average level and statistical value average level. If the fuzzy linear regression is not appropriate, then return to adjust the data sheet, until the formula is acceptable.
