Abstract:Research purposes: The stone arch bridge is one of basic type for traditional bridge in our country, which has centuries-old history. Characteristics of the ecumenicial stone arch bridge are not too long-span, shapely and using local materials with cheap cost. Centering structure is the key of entire engineering success in the construction of extra-large stone arch bridge located at cliffy coulee of mountain area.
Research results: In this paper , assembling centering structure of one extra-large stone arch bridge with 74 m height and 146 m span is introduced. Its superstructure is made切using military girder and the universal rods, and substructure is the timber arch cap. It is proved that the design for the steel-timber supporting frame is reasonable and applicable. The entire processes of building arch and removing arch accord with the design request, the engineering quality is pledged. This method can offer the readers important references of the all supporting frame for large type structures construction.
