摘要
巫山长江公路大桥是一座主净跨为 4 6 0 m的中承式钢管混凝土拱桥 ,主拱肋采用斜拉扣挂法无支架缆索吊装施工 ,已于 2 0 0 3年 4月中旬成功合拢。该桥是对我国无支架缆索吊装系统的进一步完善。其吊装施工中的一些关键技术 ,在得到进一步突破的同时 。
Wushan Yangtze River Highway Bridge is a half-through concrete-filled steel pipe arch bridge with a main clearance span of 460 m. The erection of main arch ribs adopt cable-stayed buckled method of non-support cable hoisting system, which were closed successfully in this April. The example perfects further for the non-support cable hoisting system in our country. Among them, the key techniques in hoisting construction are further broken through, it may be used for technique reference for arch bridge construction.
