Abstract
This paper, taking a main span tied-arch of 64. 0 m of a super major bridge on the Dezhou-Dajiawa Railway as an example, which spans over the Binzhou-Dagao Expressway, introduces in detail the structural design and calculation parameter selection of railway tied-arch bridge. The longitudinal and horizontal structure were calculated and analyzed by the Doctor Bridge-finite element software. The modality and elastic buckling of structure were analyzed by the large general - purpose finite element software ANSYS. The results of calculation and analysis showed that the stress, displacement, natural frequency and stability factor of the structure could meet the requirements of the relevant standards.关键词
