| Abstract: | With the Tanghe Bridge as a practical example,and the characteristics of the bridges in mountainous regions,such as being high in piers,large in spanning distance,and spanning rivers or roads,etc.,taken into account,the design and the structural analysis of the supporting systems for the cast-in-place box girders are dealt with in the paper.The supporting system for the lower span of the cast-in-place box girders of the Tanghe Bridge at the Chengde end is of the upside down bowl-type bracket,while the higher span uses the piers made up of type-83 pier,type 65 pier,and military girder equipment,the structural strength and the stability of which are analyzed in the paper.The project may serve as a useful reference for the construction of other similar supporting structures for highway bridges in mountainous regions. |
