摘要：

In this paper, using analytical method, the elastic horizontal support stiffness, vertical support stiffness and rotational support stiffness are deduced to simulate temporary fixation. Based on the construction of Dan Jiang Kou Bridge for South-to-north Water Transfer Project (SNWTP), the deflections are calculated in structure transferring stage of T type to Pi type under the influences of temporary fixation. Furthermore, the results are compared and analyzed with those collected in the construction. Conclusions of the influences of temporary fixation in different construction stages are put forward. The results are of theoretical guidance for the cantilever construction, also certain reference value to the deflection control in construction of multi-span continuous beam bridges.
