Temporary Support Design on Large-span Casting Box Girder Of the Songpu Bridge

摘要

By the study of construction of casting box girder of Songpu Bridge in Harbin, and the actual site geology, hydrology and the corresponding norms, this paper designed temporary support with the method of allowable stress. It was proved that the temporary support met the need of the site construction, both to ensure casting construction quality, but also save construction costs and speed up the construction progress, which provided a new way for the construction of large-span continuous box girder.
