Study on the Influence of Prefabricated Composite Steel Box Girder on Improving the Construction Efficiency of Bridge
With the development of economy and the increase of traffic demand,bridge construction becomes more and more important.The traditional bridge construction method often needs a long construction period and a lot of manpower and material input.However,the introduction of prefabricated composite steel box girder has brought revolutionary changes to bridge construction.This paper first introduces the construction technology of prefabricated composite steel box girder bridge,then analyzes the influence of static load of single beam during construction,and finally optimizes the maximum constraint value and the overall deviation by using the full stress tooth row method with relaxation coefficient.
