摘要
矮塔斜拉桥是近年来发展起来的一种新型桥。以广州沙湾特大桥为工程背景,分析矮塔斜拉桥成桥状态,以及活载、温度效应、混凝土收缩徐变对主梁线形、内力的影响,分析结果可为同类型矮塔斜拉桥的设计提供参考。
Low-pylon cable-stayed bridge is a new type bridge developed in recent years.Based on Guangzhou Shawa Super Major Bridge as a project background,this paper analyzes completed status of low-pylon cable-stayed bridge and influences of live load,temperature effect,shrinkage and creep of concrete on line shape and internal force of girder,and the analysis results can provide reference for design of low-pylon cable-stayed bridges of the same type.
