摘要
芜湖长江大桥是一座跨越长江的公路、铁路两用大桥。为综合解决长江航道,净空限制和满足公路、铁路行车条件,首次采用大跨度低塔斜拉桥板桁组合结构。为解决设计和建设过程中的关键技术问题,进行了荷载,刚度标准,材料,焊接标准和结构构造等方面的系统研究。本文对这些研究成果作了简要介绍。
The Wuhu Yangtze River rail-cum-road bridge is the first plate-truss composite cable stayed bridge of large span and low tower to synthetically consider the offeets of navigation, limit of clearance, traveling conditions of the road and the railway. Systematic studies on load, stiffness, materials, welding standard, structure and so on have been conducted to solve the key technical problems during the course of design and construction. This paper gives a brief introduction to the major achievements of these studies.
