| Abstract: | Mamu Bridge of Jiande in Zhejiang is located at the narrow neck of Ω-type bending outlet. Through the calculation analysis of the riverbed stability and the velocity flow site where thebridge is located, the data are provided for the arrangement of the bridge span and the pier position. Under the premise meeting the shipping and the floodwater releasing requirements, the construction scale of bridge is controlled, which can be referred for the design of similar bridge transition, especially for the design of the following bridge transitions on Xinan River. |

| Keywords: | bridge axis riverbed stability flow site distribution arrangement of shipping span design of bridge transition |
