摘要
钢管混凝土拱桥是拱桥中一个新兴的分支,近年来在国内公路桥梁中得到迅速发展,由于该桥型静力体系多样,几乎适用于各种地区任何地质条件。2002年在港口工程中开始采用钢管混凝土拱栈桥。港口工程在设计中必须要考虑到海上受天气、风、浪、流影响巨大,不具备像陆地上的施工平台等因素,如何解决施工问题成为关键。分析了港口工程栈桥使用和受力特点,介绍栈桥的设计过程,总结设计经验供设计者参考。
The CFST（Concrete Filled Steel Tubular） arch bridge is an emerging branch of highway bridges in the country in recent years,due to the variety of static bridge-type system,which may be applicable to any geological conditions in various regions.In 2002,concrete filled steel tubular arch trestles were begun to used in port projects.The significant impact of the weather,wind,waves,and the fluid on the sea should be taken into account in the design of port engineering projects,and the huge construction platform generally used on the land can not be constructed on the sea.So,the consturction technology becomes the key issure in the design.In this paper,the servicebility and the mechanical behavior of port engineering trestles were analysed,and the design experiences were summarised.
