Abstract

Abstract: Masangxi Bridge is a floating cable-stayed bridge with double-tower and double cable planes, whose main span is 360m. The main beam is separated triangle beam of prestressed reinforced concrete, and inverted Y-shape tower is adopted. As an extra-long bridge, the closure of side (center) span touches on the completion and using of bridge in time, and perfect design had been made by designer for preventing contingency.The design idea is introduced in this paper.

Key words: Masangxi Yangtze River Bridge, cable-stayed bridge, closure

摘要： 马桑溪大桥是一座主跨360m的双塔双索面飘浮体系斜拉桥,主梁为预应力钢筋砼分离式三角箱形梁,主塔为倒Y型,采用挂篮悬浇施工.作为一座长江上的特大桥,边(中)跨能否顺利合拢直接关系到大桥能否按期建成通车,为避免出现意外,设计者对合拢方案做了精心设计,笔者着重介绍合拢方案的设计思路.
