荆州楚都大道跨海子湖特大桥设计

Design of Cross Haizi Lake Bridge on Chu Du Avenue, Jingzhou

楚都大道是荆州市城市向北发展的主干道,也是进入荆州市园博园的主通道,桥型方案采用多跨变截面连续梁桥,整体一联布置,桥梁跨径布置为65 m+123 m+156 m+123 m+10×90 m+55 m,全长1434 m(含桥台)。此类跨度和长度的桥梁没有成熟的工程实例,大桥连续梁长度为国内和国际同类型桥梁的总长度第一。

Chudu Avenue is the main road for Jingzhou City to develop northward. It is also the main passage to Jingzhou Garden Expo. The scheme of multi-span variable-section continuous beam bridge is adopted with an overall arrangement. The span of the bridge is 65 m + 123 m + 156 m + 123 m + 10 ×90 m + 55 m, with a total length of 1 434 m(including abutment). There are no mature engineering examples of bridges with such span and length. The length of the continuous beam of the bridge is the first of the total length of the same type of bridges at home and abroad.
