矮塔斜拉桥的发展及前景展望

Development and Prospect of Extradosed Cable-Stayed Bridges

矮塔斜拉桥是介于梁式桥与传统斜拉桥之间的典型混合体系桥梁,近些年在国内外发展态势良好。文章基于近年来矮塔斜拉桥的发展进行综述,阐述了矮塔斜拉桥的起源和发展历程、成桥索力和施工索力优化方法、构造特征,并总结了矮塔斜拉桥面临的问题,展望了矮塔斜拉桥的发展趋势,希望对矮塔斜拉桥的推广有所裨益。

The extradosed cable-stayed bridge is a typically combined bridge between the girder bridge and the traditional cable-stayed bridge, and it has developed well at domestic and foreign in recent years. Based on the development of extradosed cable-stayed bridges in recent years, this paper summarizes the origin and development process of extradosed cable-stayed bridges, the optimization methods of bridge cable force and construction cable force, structural system and structural characteristics, and summarizes the problems faced by extradosed cable-stayed bridges. Looking forward to the development trend of extradosed cable-stayed bridges, we hope that it will be beneficial to the popularization of extradosed cable-stayed bridges.
