简支预制槽形钢混组合梁在城市桥梁中的应用

Application of Simple-supported Precast Channel-section Steel Concrete Composite Beam in Urban Bridges

摘要:

在城市高架桥梁中，钢-混组合结构梁桥因其结构强度高、施工速度快、后期养护简单等优点在国外被广泛采用，目前是欧美等国城市高架桥梁的主力桥型，但国内施工的组合结构桥梁数量不多。以山西省太原市某桥梁工程为背景，介绍了30 m左右标准跨径的预制槽形钢混组合梁的设计，同时也为以后该类桥梁结构形式的工程设计与实践提供一定的参考价值。

Abstract:

In the urban viaducts, the steel-concrete composite structure beam bridge is widely used abroad because of its high structural strength, fast construction speed, simple maintenance and other advantages. At present, this type of bridge is the main bridge type of urban viaducts in Europe and America. But there are no many composite structural bridges under construction in China. Taking a bridge project in Taiyuan, Shanxi Province as the background, the design of precast channel-section steel-concrete composite beams with a standard span of about 30m is introduced, and also provides some reference value for the engineering design and practice of this type of bridge structure in the future.
