Study On Route Design Key Points And Engineering Application Of Mountain Expressway

With the continuous development of China’s expressway construction,the expressway construction in plain areas has been basically completed,and the expressway construction continues to enter the mountainous area,which is both the need of China’s economic and social development and the need to improve the traffic conditions in mountainous areas.Constraint of mountain expressway under construction,high cost and great damage to the ecological environment,thus affecting the mountainous area expressway route design of topography,geology,environmental protection,local planning,traffic safety and other key points,reduce the engineering cost of mountainous expressway,reduce the mountainous area expressway construction to the destruction of the ecological environment is of great significance.This topic has carried on the research to the mountain area expressway route design,the topography,the geology,the environmental protection,the local planning,the traffic safety and so on is the main point which affects the mountain area expressway route design,the mountain area expressway route design simultaneously should follow the safe and reliable,according to the local conditions,the multi-plan comparison selects the principle.The research results of this project have achieved good results in the design of Jiangluo expressway route,which has played an important role in reducing the project cost of Jiangluo expressway,enhancing the driving effect of Jiangluo expressway on the economic development along the route,and reducing the damage of Jiangluo expressway to the ecological environment along the route.
