Abstract Research purposes:Curve parallel arrangement method is a commonly used method for design of railway bridge, especially for the curve bridge crossing highway and river, but is generally used far small span bridge, so the research is done in this paper on application of this method in large span curve bridge for the purpose of enlarging the application scope of this method based on the example.
Research conclusions: The application of curve parallel arrangement method in curve bridge, especially in small curve bridge reflects the bridge arrangement advantages of having overpass condition and ship passing requirement, but when application of the calculation mode of curve bridge parallel arrangement for the multiple-span small curve railway bridge, the bridge seam may exceed 30cm or be less than that of design, so it is necessary to adjust the seam according to the real situation. The experience and calculation process of Yongding River Bridge can be learnt for design of other curve bridge with curve parallel arrangement method.
