京石客运专线桥梁设计综述

Summary of Bridge Design for Beijing-Shijiazhuang Passenger Dedicated Line

京石客运专线受立交、河流等自然条件的影响,特殊结构采用较多。对该线桥梁设计进行了系统的论述,包括沿线自然环境特征、主要技术标准、设计特点、一般桥梁设计以及5类有代表性的特殊结构,详细介绍5种特殊结构类型,包括它们的结构尺寸、细部构造、施工方法及设计创新等,为今后高速铁路桥梁设计提供借鉴和指导作用。

Because of the impacts of natural conditions such as interchange, river, Beijing-Shijiazhuang passenger dedicated railway has employed a lot of special structures. This paper summarized systematically the bridge designs of this line, including the natural environment characteristics along the line, the main technical standards, design characteristics, general bridge designs as well as five types of representative special bridge structures. In the meanwhile, this paper introduced the five types of representative special bridge structures in detail, including their structure sizes, detailed structures, construction methods and design innovations. The related results may provide reference and guidance for future high-speed railway bridge designs.
