Research On The Construction Technique Of Spanning Bridge In Limited Space

Recent years. With the development of our economy and society. It was being rapidly progressed that the traffic career. Many highways, railways and bridges were constructed. The bridge design and construction techniques progressed greatly.Many kinds of bridge construction techniques were analyzed in this paper. Their advantages and shortcomings were summarized, too. These methods are not fit to the bridge construction when the space is limited or narrow. A new technique is put forward that high-low brace gantry crane wide double guiding girder method to construct bridge. It is fit to narrow space better. And a series of relative facilities and measurement are studied and producted. So as to make itfeasible. Through a real project------"B" bid section of Shijiazhuang South Bridge. It is provedthat high-low brace gantry crane wide double guiding girder method is a good and new technique of bridge construction.
