After review and approval by the Technical Committee of the State Railway Administration, the State Railway Administration recently approved the issuance of the railway industry standard "High-speed Railway Design Code", which will be implemented on February 1, 2015, and will provide a complete set of system specifications for China's high-speed rail development and high-speed rail "going out". Construction standard support.
With the development of high-speed railway construction, China's high-speed railway design specifications are also constantly revised and improved. From the "Eighth Five-Year Plan" period, the scientific and technological research will form a series of design specifications for the Beijing-Shanghai high-speed railway, and further summarize the experience of building passenger dedicated lines such as Qin Shenke, Beijing-Tianjin, Zhengxi, Wuguang, Hening and Hewu. To form an interim regulation for the design of new passenger railways with a speed of 200-250 km and 300-350 km, and then further integrate into the "High-speed Railway Design Code (Trial)" in 2009. After that, the railway department will organize various forces to further develop high-speed railway technology. The key technologies and weak links in the focus are focused on scientific research, comprehensively summarizing the practical experience of high-speed railway construction and operation of different types and different technical characteristics such as Beijing-Tianjin, Beijing-Shanghai, Beijing-Guangzhou, Harbin and Zhengxi, in order to improve the design specifications of high-speed railways. " laid an important foundation.
The newly issued "High-speed Railway Design Code" implements the safety priority principle. For the first time, it is clear that the high-speed railway only runs EMU trains. It is specialized in subgrades, bridges, tunnels, ballastless tracks, station yards, passenger stations, traction power supply, communication signals, etc. Strengthened the design of safety guarantee function; highlighted the design requirements of “people-orientedâ€, convenient, fast, comfortable and comprehensive transportation to improve service quality; it mainly reflected the land saving, energy saving, water saving, material saving and the whole life cycle of high-speed railway construction. The “four sections and one guarantee†green construction concept of protecting the environment; focusing on the combination of China's national conditions, economic and social development level, transportation demand and environmental conditions, rational optimization of speed matching, equipment matching and major design parameters of various majors, optimizing the complex road network Under the conditions of high-speed railway operation and dispatch system design, high-density and large passenger flow passenger service system design, the technical standards are more in line with system, advanced, mature and economic rationality requirements.
