Route Selection Method and Application Examples for Mountainous Urban Roads
With the development of social economy and urbanization,urban construction has gradually expanded to the periphery.In or-der to solve the problem of construction land,some cities have gradually expanded the intensity of development and utilization of moun-tainous areas.The planar alignment of urban roads must comprehensively consider the influence of multiple factors such as planned road network,land development along the line,social environment,and public participation.It will break the habit of laying out accord-ing to urban planning in the past.Roads with large terrain fluctuations in mountainous areas should also consider the requirements of longitudinal alignment and geological line selection.From the perspective of the mutual integration of urban road and highway design,the relevant research results and practical experience summary of route selection are reviewed.Combined with engineering design exam-ples,the basic principles and methods of topographic and geological line selection,sustainable development line selection,safety line selection,and economic line selection that should be followed in the line selection of urban roads in mountainous areas are explained,and the basic ideas and processes of line selection are introduced.It is suggested that the concept of green development and full life cy-cle construction should be integrated throughout the entire process of the project.
