智能京张高速铁路总体创新设计

京张高铁是我国"八纵八横"高铁网京兰通道的重要组成部分,是我国第一条智能高铁,将直接服务于2022年冬季奥运会,设计中采用了多项创新技术。根据该线的功能定位特点,结合项目沿线周边环境、地形地貌特点及各方要求,因地制宜地合理选择不同的技术标准,京张高铁全线涵盖了我国目前铁路客运时速120～350 km的全系列标准;在高铁客站建设,路基、桥梁、隧道等线下工程,通信信号等四电工程都有多项创新设计,全面贯彻绿色、环保、文保发展理念,首次提出铁路文化设计的概念,全力打造"智能京张精品工程"。从总体设计角度出发,重点介绍京张高铁的设计特点和创新点。

The Overall Innovative Design of the Intelligent High-speed Railway from Beijing to Zhangjiakou

Beijing-Zhangjiakou High-speed Railway is an important part of Beijng-Lanzhou Corridor in the National High-speed Railway Networks. It is the first intelligent high-speed railway railway in China to offer direct service for 2020 Olympics. Many innovative technologies are adopted in the design and deferent technical standards are selected according to the functional orientation, surrounding environment, geological conditions and other requirements. Beijing-Zhangjiakou High-speed Railway employs nearly full series of standards on 120～350 km passenger transport, and many innovations are contributed to passenger station, subgrade, bridge, tunnel, communication and signal of four electrical engineering.The concept of green, environmental and cultural protection is fully implemented, and railway cultural design is put forward the first time to make the railway intelligent and excellent.
