The Construction Problem Of The U-shaped Girder Of The No.6 Rail Transit Of Shanghai

With the development of the construction of Shanghai City, the rail transit will play more important role. So the construction of rail transit will be an important municipal project.Based on the construction No.6 underground,this paper studies about the prestressed concrete,fiber concrete,the analysis of support of steel cyclostyle and the test of the U-shape girder.Through the study of this paper, some conclusions can be drew out. The use of fiber and prestressed concrete can solve the crack of the flimsy concrete; Use the falsework can solve the support system of the cyclostyle. Finite element method was used to study the support system. And the test was done at the site.The conclusion of this paper and the construction methods of No.6 rail transit can be used in other projects.
