Research on Interchange Selection for Mountainous Expressway
In order to improve the design level of expressway interchange,this paper summarizes the common types and selection principles of interchange,and discusses the design points of expressway interchange scheme from the aspects of design speed and ramp section design.At the same time,taking a mountainous expressway as the research object,the technical and economic comparison of the interchange schemes is carried out,and the safety of the interchange selection scheme is tested.The research results can provide theoretical basis for similar project design.
