海南省徐闻大桥的设计与分析

Design and Analysis of Xuwen Bridge in Hainan Province

结合一座钢-混凝土组合梁仿斜拉桥,从结构体系的选型、组合梁设计与优化以及斜塔的设计等方面阐述了这种仿斜拉桥的设计难点与解决方法。还分析了在这种仿斜拉桥中设置过载保护器的必要性,并论述了其工作原理和计算方法,希望能对该类桥梁设计提供有价值的参考。

With reference to an imitated cable-stayed bridge of steel and concrete composite girder, this paper describes in details the design problems of the bridge and solutions to the problems from aspects of selection of structural system types, design and optimization of the composite girder and design of inclined bridge pylons, and also analyzes the necessity of applying overload protectors to the bridge, the basic working principles and calculation methods for the protectors. It is expected that the presentations herewith can provide valuable reference to the design of bridges of similar kind.
