ABSTRACT
The incremental launching method is a bridge construction method (Li & Zuo 2006). The specific construction process is as follows. First, beam bodies are built using cast-in-place technique or assembled on the bridge end. Second, the beam bodies get through temporary sliding supports on the top of piers by pushing jack action. Finally, the beam bodies are in place. The main characteristics of a continuous beam bridge under dead load determined by the incremental launching method are the same as those of the main girder segment presented above, and internal force of every section in the whole bridge is a cycle with repetitive change (Qin & Chen 2013).
