| Abstract: | The article introduces the design and the practical result of a Beile truss beam bridge as a traffic wad blanketed on the top of deep pit underpassing the urban trunk road of Nanjing.The structural rigidity of this bridge is large and the deformation is small,which not only settles down the traffic demand and the truss assembling speed is quick,but also solves the problems of the lim- ited construction period of urban deep pit and the protection of underground pipelines,and sets forth the construction metho... |
