Research On Interrelationship Between Water-damage Factors Of Road And Other Factors

Highway communications has brought marvelous convenience to people's life and work since 1888 when highway communications came into operation .In HuBei province , highways net connects all counties in the province and its development level locates in the leading position in China. However, the protection of highway's environment is mainly on pollution prevention and the highway's ecological environment conservation has not yet been put into agenda. This research tries to pursue some valuable exploration in this aspect.Water-damage that occurs in the highway's operation phase shows deterioration of ecological environment. Since water-damage of highways occurs when it rains, people thought the precipitation be the only reason to highways water-damage matter of fact, the factors that can influence water-damage are complicated and changeable. They are closely related to many other factors such as vehicle extrusion, deterioration of ecological environment, vegetation destruction, climate, topography etc.Under the great support by HuBei bureau of Communications, The thesis collected and sorted all statistics of water-damage factors and other factors of HuBei highway net from 1995 to 1999.lt utilizes some mature theories and methods of mathematical statistics such as departure analysis, regression analysis, difference rate analysis, cluster analysis, principle component analysis and devoting percentage analysis. SPSS10.CK Excel2000 which are authoritative, advanced and stable software of statistical analysis are employed for calculation. It analyses and researches on the relations between water-damage factors and other factors of HuBei highway net based on the natural ecological situation. It claries the relations between water-damage and other factors and set up the matrix. It finds out the present situation of other factors and the significance of other factors' influence to water-damage factors in different rainfall areas. Besides, the thesis also finds out those rainfall areas where the relations of present situations of water-damage are similar to one another, closer or far or in features. It differentiates and classifies them and combines twenty-four water-damage factors into ten factors for simplification.The result of this research will help people treat the problems of highway water-damage from a brand-new and overall angle. It can provide a definite direction for maintenance of highways and be helpful to authorities for investmentaccordingly. It will prevent and reduce water-damage effectively and help highways work better and coordinate with environment. Moreover, it can prolong the operation life of highways and be favorable for ecological highways construction and function by carrying out the sustainable development strategy.
