摘要
雄安新区—北京大兴国际机场快线作为国内首条市域列车运行速度达到200 km/h的城际快线,其高架区间占比达到76%。在无明确规范参考的情况下,通过理论和试验研究并参照既有规范,制定了适合该线的标准,完成了该线高架区间的设计工作。结合该工程的特点和难点,详细介绍了高架区间的桥式选择、桥面布置、标准梁设计、下部结构设计和附属设施设计等内容和相关技术标准,为后续类似工程提供解决思路和技术储备。
Xiong’an New Area—Beijing Daxing International Airport Express Rails is the first inter-city express line in China,where a urban train runs at a speed of 200 km/h,the elevated section accounts for 76%.In the absence of clear specifications for reference,through theoretical and experimental research and reference to existing norms,the standards suitable for this line are formulated,and the design of the elevated section of this line is completed.Combined with the characteristics and difficulties,the bridge selection,deck layout,standard beam design,substructure design and ancillary facilities design of elevated section are introduced in detail,which provides solutions and technical reserves for similar projects in future.
