Research On Soil And Water Conservation Measures In Guanghe Expressway Construction

In recent years,the loss and conservation question of soil and water is gradually being anew subject.The prediction of soil and water loss in highway construction is required byTechnical regulation on water and soil conservation plan of development and constructionprojects,which mainly use mathematic model method,experience method and analogism.Inthis thesis,the author apply the methods of Guang-He expressway project,studied the problemof highway construction project on soil erosion and soil and water conservation.On the basis of the soil and water loss states along the expressway line are detailedinvestigated.Then,basic prediction contents and methodologies to soil and water loss areexamined.Analogism is adopted in prediction method to soil and water in Guang-Heexpressway construction,which is used to predict and analyse the newly extra soil and waterloss according to different districts.The prediction results show that main work area andsoil-fetching area are the most serious soil and water areas. For these preventive areas,theperfect precaution measures for preventing the soil and water loss are taken.
