浙江建德新安江马目大桥桥渡设计

Design of Bridge Transition for Mamu Bridge on Xinan River of Jiande in Zhejiang

浙江建德马目大桥位于"Ω"型弯道出口狭颈处,通过对桥位处河床稳定性及流速流场的计算分析,为桥梁孔跨布置与墩位布设提供依据,在满足通航和泄洪要求的前提下,控制了桥梁建设规模,可供类似桥渡设计尤其是新安江上后续临近桥渡设计时参考。

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.
