摘要
系杆葵拱桥是一种新颖的桥式结构,采用体外束系杆平衡主拱推力,从而解决了软弱地基修建上承式拱桥的难题。本文结合江山市迎宾大桥的设计,介绍了该桥型的结构体系构思、基本受力性能和造型特点。
The sunflower-shaped tied arch bridge is an innovative bridge structure. It uses external strand tie beams to balance arch horizontal pushing force and thus solves the problem of constructing a deck arch bridge on a soft soil foundation. According to the design of Yingbin Bridge in Jiangshan City, the structural system considerations, fundamental mechanical property and configuration characteristics of this type of bridge are introduced.
