Discussion on the Design Points of Railway Cross the Urban Road

Due to historical reasons, most developing countries such as the People’s Republic of China were founded and developed after World War II. late development modernization urbanization, they did not incorporate mature urban planning concepts Western countries. At same time, due limitations population, economic scale, insufficient expectations for development, early railway projects often built on edge city, without leaving sufficient space city. After China’s reform opening up, rapid urbanization has led continuous expansion city scale. The railways inevitably cut into cities, resulting in an increasingly prominent contradiction between engineering. Taking Dujiagou Interchange Project Zhongwei Lanzhou High Speed Railway example, this paper expounds advantages disadvantages different bridge structures existing terrain, providing reference significance design similar future.
