Abstract

Considering the geological conditions and navigable requirements of Qijiadu Yellow River Bridge of Lanzhou-Hezuo Railway Bridge location, deck-type stiffened skeleton concrete arch bridge whose main span is 180 m long was adopted. After careful research on the arch axis coefficient of the bridge, structural dimension and main construction procedure of the main bridge were described in details. Midas software was used to build the finite element model for calculation and analysis. The analysis result showed that the design requirements are well satisfied.
