摘要
虎门大桥是广深珠高速公路上的特大桥梁,建设规模宏伟.主航道桥是我国第一座现代化公路悬索桥,辅航道桥是目前世界跨径最大预应力混凝土连续刚构桥.本文扼要叙述该桥桥位选择,桥型方案比较,悬索桥与预应力混凝土连续刚构桥设计与施工.
Humen (Boca Tigris ) Bridge is located at the estuary of the Zhujian(Pearl) River carrying the Guangzhou-Shenzhen-Zhuhai Superhighway which links up Guangzhou City to the Shenzhen and Zhuhai Special Economic Zones.At bridge site, the river consists of two channels. The eastern channel ( main channel ) bridge is the first modernized long span steel suspensionbridge built in China, and the western channel ( Sub channel ) bridge is the longest span P C continuous rigid frame bridge in the world.The selection of bridge location, the comparison of bridge alternatives and the structural arrangement of the whole bridge are described in the paper. The design and construction of these bridges are explained in detail. The aerodynamic stability of the bridge and the results of wind tunnel test are examined.
