The Key Technology Of Mountainous Urban Roads Design

Mountainous area in China accounts for more than the country’s total land area of2/3, the mountain town accounted for nearly half of the national total town. City of mountain complex terrain conditions, land is often River, gully, Hill Valley segmentation, therefore the design safety, smooth and optimization of road network development in the mountainous cities and towns is very important. At the same time due to topographical constraints, mountain town land conflicts are more prominent, more difficult to mountain city planning and road network layout, how to consider the indicators of road construction in the city, which adapted to the construction of mountain city, to establish convenient transport links to the district between city, improve traffic efficiency, is a mountainous city road planning and design of the key.The complex topography constraints of road network planning and layout of mountain city and fixed line. In order to better play the role and status of mountainous city road planning and design of the city planning, so it is necessary to discuss the key technology and methods of road design in Mountainous City, this paper firstly introduces the background of Mountainous City Road Development and an overview of the field of domestic and foreign research and development, the whole idea of the design the analysis of city of our country; then the mountain road and interchange design problems and challenges; and on the basis of this, some of the success of the mountainous city road network planning and design examples are discussed and analyzed; finally, how to design and establish effective convenient mountain city transportation system and transportation system some method and countermeasures.Through the design and research of this thesis, research and solve on some issues, there are the control of rationalization, conducive to the mountainous city road design as well as the safety of investment cost, more to create a city of beautiful environment, and provide reference balancing ecology. In a word, design of Mountainous City Road designers need more flexible design concepts, more detailed, can make the organic combination of road traffic system and city development, which brings great economic benefits and social benefits to the mountain city.
