| Abstract: | In the construction of the long span concrete filled steel tubular arch bridge by using an integrated installation towers, the key technologies, such as strength and stability of the tower, deformation of a cable, measurement for the tension and control of the arch ribs, are researched in order to assure the construction quality and safety. The design of an integrated installation towers can decrease the input equipments, reduce the engineering costs and pick up the construction speed. This technology can be also used in the construction of the same kind bridge. |
