摘要
浙江平湖海盐塘桥为一座主桥跨径为 (30 + 72 + 30 )m的自锚式悬索桥 ,上部结构采用钢筋混凝土箱梁 ,主缆锚固在主梁端和主梁的跨中 ,主缆外包钢管混凝土索套 ,塔梁固结 ,设计构思独特。以该桥为工程背景 ,介绍这类桥梁设计构思 ,通过计算分析说明其受力特性 ,并对这种桥型的发展。
The Haiyantang Bridge in Pinghu is a self anchored suspension bridge, spans are attributed as (30+72+30) m. In the superstructure the concrete box girders are used, the cables are anchored both in the end and in the middle of the girder, and are surrounded by the concrete steel tubes. Taking the bridge as background and analyzing the stress features, the conception design and the development of the special bridge are discussed.
