摘要
钢管混凝土简支拱桥在高速铁路工程中运用广泛,已经成为最常用的"特殊"结构.钢管混凝土简支拱桥的设计相对于简支梁桥和连续梁桥有其独特的特点,为此从结构尺寸、设计荷载和设计指标及设计要点等方面总结了该类桥梁的设计问题,可为该类桥型的设计和发展提供借鉴和指导.
Abstract
The concrete filled steel-tube simple-supported arch bridge is widely used in high-speed railway engineering and has become the most commonly used"special"bridge structure.Unlike the sim-ple-supported beam bridge and continuous beam bridge,the concrete filled steel-tube simple-supported arch bridge has its unique characteristics.Therefore,the design issues of this kind of bridge are summarized from the structural dimensions,design load,design indexes and design essentials,which can provide the reference and guidance for the design and development of this kind of bridge.
