Research on Linking between Bridges and Existing Road Network of Mountainous City

摘要

Because of the complex topography of mountainous city, there is usually large difference between bridge and existing road network in elevation. In order to realize rapid traffic of vehicles, reasonable interchange ramp can be designed to realize rapid dividing of vehicles at bridgehead. This paper mainly introduces a typical interchange at bridgehead — Caiyuanba Interchange, located in Chongqing, a mountainous city, explains difficulties encountered in engineering design and realizes rapid dividing of vehicles by designing reasonable interchange at bridgehead, so as to accumulate certain experience in the construction of interchange at bridgehead.
