Engineering Practice of Segmental Assembly in Large Spancurved Bridge by Scaffolds

Abstract:

Part of Xiping railway south cave temple bridge segments are on easement curve. considering the project time limit and construction difficulties of large span curved bridge, the construction team adopted 64m soffit scaffolding composite column structure to assemble the precasted box girder segments ,this method can better solve the technical problems of nonuniform stress distribution in transverse beam and upright tubes of the bracket. Therefore, this paper introduces in details the bracket structure as well as the key construction technologies of segmental beam rand bracket. the experience can provide good reference for similar engineering.
