Research on the Stability of Erecting of Pre-Cast Segmental Box Girders with SPZ1300/48 Gantry
In the present paper the whole structure and the construction process of SPZ1300/48 gantry is introduced and the stability of the gantry under lifting process and transition process is also analyzed by some reliable finite element method software. By the analysis of the overall stability of the structure, taking into account the bad weather (strong winds) in the region, in the case of lifting process and after the segments placed, the optimal lifting sequence of the beam segments on account of the stability of the structure itself is obtained. By this way a useful sample for analysis of similar systems is provided, and then a technical foundation is established for bridge constructions by segmental assembling method for larger span or tonnage.
