Review of Key Technologies for Bridge Design of Beijing-Xiongan Intercity Railway
In constructing the Beijing-Xiongan Intercity Railway,an emblem of intelligent high speed railways in the new era,technological explorations and innovations have been conducted based on experience in constructing high speed railway bridges.Research has been carried out on the prefabricated integrated bridge structure,bridge structure incorporating fully enclosed noise barriers,pier top rotation with a long cantilever drawn from the side pier,and the design of Xiongan elevated station.The introduction of the prefabricated integrated bridge structure and the bridge structure with fully enclosed noise barriers marks their inaugural application,yielding notable ecological,environmental,and social benefits while meeting the technical standards for high speed railways.Pier top rotation with a long cantilever drawn from the side pier signifies an innovative approach to crossing major expressway interchanges,providing a new design concept.The layout of the bridge in the throat area of Xiongan elevated station creates favorable conditions for future land use in the Xiongan New Area.
