Using A Method Of The Muitiple Linear Regression Analysis To Compile Minor Repairs And Maintenance Budget Drafting

The article proceeds from the engineering of highway maintenance level, analyzed the characteristics of the minor repairs and maintenance, the main factors affecting the consumption of manual work、material and machine, and use linear regression analysis method establishment of road repair and maintenance budget index regression.Based on the literature review, analysis and summarize the definition of minor repairs and maintenance is that often carry out maintenance and repair minor damage to its part of the operation to the highway and along it’s facilities. Repair and maintenance as a part of the highway maintenance, with regular, preventive, timeliness, small in scale, the occurrence of complex content, face dispersion characteristics. In this study, through a review of relevant literature and grooming, based on the interviews with experts, through the way of design questionnaire, and finally determined select the following key indicators:the road width, The average length of the small bridge with section, road grade, road type, the traffic volume of an annual average daily, road surface layer thickness service life of highway, annual rainfall. In combination with a review of relevant literature and grooming, extract the literature that has a reliable mathematical models and empirical analysis, and through a large amounts of data and literature reading and studying, the essay based on the division of highway engineering budget quota of daily maintenance indicators, then collection, collation, analysis of relevant informations, According to the existence of a linear relationship between quantity of consumption and traffic, pavement thickness, width and so on. propose a method of the equation of linear regression of mathematical statistics for minor repairs and maintenance budget drafting, meanwhile, it takes "road minor repair and maintenance budget index drafting of Yunan province highway maintenance project" as supported project. It verify the rationality and applicability of the budget index drafting method through calculation and comparative analysis on minor repair and maintenance budget index drafting, which can be considered as macro control for providing highway maintenance funds to highway relative department.The research results of road repair and maintenance budget index table is see for details Appendix one, This paper puts forward some suggestions according to the calculation results. There are many research ways to repair and maintenance budget quota, in the course of the study we found for the analysis of about repair and maintenance budget index has not been systematically, in addition to the study on the method of mathematical statistics in the linear regression model, but also can find the other mathematical models were developed for repair and maintenance budget index, it would be a depth direction. The calculation of repair and maintenance budget index, it takes "road minor repair and maintenance budget index drafting of Yunan province highway maintenance project" as supported project, calculation and comparative analysis on minor repair and maintenance budget index drafting, but there is a great difference of economic development level of each province, the annual investment to maintenance fund is more or less. The preparation of repair and maintenance budget indicators which is suitable for all province’s own use, will be a very meaningful to the practice field.
