Design & Construction of Overpassing Expressway of Pedestrian Bridge
The ground expressway,as the traffic artery with large traffic volume for long distance in cities,can meet the long-distance connectivity between cities.The expressway has the disadvantages of dividing the plots on both sides of the road and restricting the passage of people on both sides.Therefore,it is necessary to build pedestrian overpasses along the expressway to ensure that pedestrians on both sides of the road can cross the street safely after completion.Taking the 6 pedestrian bridges in Zhuzhou section of Dongzhu Road in Changsha,Hunan as an example,this paper introduces the project overview,bridge site selection,design points and construction scheme of the pedestrian bridge.As a project,the 6 bridges should be versatile and reflect the difference.This project can provide a reference for the design of mass pedestrian bridges similar to up-span expressways.
