Abstract:
The concept of “concrete huge box section girder” for achieving double-deck traffic for city bridges was first put forward for saving land resource and improving traffic efficiency and conditions of bridge passage. It referred to box girder with necessary openings in the web plates which could achieve double-deck traffic for city bridges by means of increasing the section height of the traditional concrete box girder and its roof, floor deck systems became the bridge deck system. Actual examples of the double-deck traffic were provided on an engineering practice basis and research situations on concrete box section girder and double-deck traffic for city bridges were introduced. Some key technological problems in design of concrete huge box section girder were discussed, which filled the gaps in the field of the design technology of the concrete huge box section girder without inner plate. Some guiding recommendations of the promotion applications of concrete huge box section girder for city bridges were proposed.
