Abstract:For large-scale bridges or extra-long continuous elevated bridges in the sea area or tidal flat area, the whole-hole precast concrete box girder is a very attractive type of precast concrete box girder due to its good manufacturing quality and durability, under the condition that temporary construction facilities such as large precast sites are sufficient. Competitive bridge structure type. In this paper, combined with a highway project along the coast of Ningbo, Zhejiang Province, the finite element software ANSYS is used to analyze the working conditions of the carriage beams, and the force characteristics of various temporary bearing schemes are studied, which can provide information for large-scale sea-crossing bridges and other whole-hole prefabricated bridge structural projects. useful reference.
