Research On Highway Project In Alpine Forest Region

Forest road is an indispensable infrastructure for forestry and regional development.The problems such as lack of roads,low grade,serious lag in China's alpine forest areas seriously affected the development of forest management,forest fire prevention and other forestry work,also it is not conducive to the transformation of economic development in forest areas.From the experience of the development of European forest road,the highway construction in our country is still in the developing stage.Highway as one of the main mode of transportation,along with the economic development offorest change and constant improvement of the forest protection and forest tree planting,the construction of alpine forest road will certainly become the future important part in highway construction in our country.As a result of new technology,new materials,the area highway construction in the past can not fully adapt to the economic development and the new era of traffic demand.These days,the construction of alpine forest road is the only way to pass for social development,economic reform,forest fire prevention.Based on the characteristics of the traffic volume and the national highway 332 line prediction results of principle and Research on the technical index of highway construction,to fully understand the research status of domestic highway cold forest area and collected in the national highway 332 line Ali River to the Root River Highway and railway on the basis of the current situation,characteristics of Chinese alpine forest road are analyzed,testing study of existing road,highway features and problems of existing road,after the layout,the route scheme on the filling height of subgrade,special subgrade treatment,pavement material selection is studied to determine the optimal design scheme.Through the research on the design of national highway 332 highway,this paper provides the basis for the highway project design of the highway.The conclusion and the method of this paper also apply to the highway engineering in other areas.
