Beijing-shanghai high speed railway

Project overview

After more than ten years of discussion, the Beijing-Shanghai high-speed railway with a total investment of 220 billion yuan will be officially started in 2007 and is expected to be completed in 20 10. By then, people will take the Beijing-Shanghai high-speed train, and it takes only five hours from Beijing to Shanghai. The Beijing-Shanghai high-speed railway is the project with the largest investment scale and the highest technical content in the Medium-and Long-term Railway Network Planning, and it is also the first high-speed railway in China with the world advanced level. The total length of the main line is about1318km, which is roughly parallel to the existing beijing-shanghai railway trend. The whole line is a newly-built double track with a design speed of 350km/h and an initial operation speed of 300km/h, totaling 2 1 train. The project is expected to be completed in about 5 years and put into production on 20 10.

The length of the bridge is about 1 140km, accounting for 86.5% of the length of the main line; The tunnel length is about 16km, accounting for1.2% of the main line length; Subgrade length 162km, accounting for12.3% of the main line length; Ballastless track is laid on the whole line, about 1268 main line kilometers, accounting for 96.2% of the length of the line. Ballasted track is about 50 kilometers of the main line, accounting for 3.8% of the length of the line. The total land area of the whole line is 5000hm2 (excluding Beijing South Railway Station, Beijing EMU, Sheng Da Guanqiao and related projects).

The Beijing-Shanghai high-speed railway will lay jointless track and ballastless track. Infrastructure such as railway lines, traction power supply and communication signals will adopt various environmental protection measures to reduce vibration and noise, energy consumption and electromagnetic interference. For disaster prevention and safety, the whole line will be monitored in real time. The world's advanced power distributed EMU is adopted, which is under the unified command of an integrated automation system integrating traffic control, dispatching and command, information management and equipment monitoring to ensure high speed, high density, high comfort and large size.

The Beijing-Shanghai high-speed railway realizes full interchange of crossings and closed lines, which not only facilitates the passage of people and vehicles along the line, but also ensures the safety of high-speed trains. Bridges are preferred to replace roads in the whole line, so as to save precious land resources in the eastern region to the greatest extent.

master design

The Beijing-Shanghai high-speed railway is located in North China and East China of China, connecting Bohai Sea and Yangtze River Delta at both ends, and running through Beijing, Tianjin and Shanghai and Hebei, Shandong, Anhui and Jiangsu provinces. The area it passes through accounts for 6.5% of the land area, and the population accounts for 26.7% of the whole country. There are 11cities with a population exceeding110,000, and the GDP accounts for 43.3% of the whole country. It is the most active and potential area for economic development in China and the busiest passenger and freight transport corridor in China, with great growth potential. Plain is the main area along the line, and some areas are low mountains and hills, crossing the four major water systems of Haihe River, Yellow River, Huaihe River and Yangtze River. Beijing-Jinan belongs to Jilu Plain, with flat and open terrain, high at both ends and low in the middle, and Tuanbowa area is the lowest place in the whole line; Jinan-Xuzhou is a hilly plain in the south-central part of Shandong Province, where the terrain fluctuates greatly, and Taian section is the highest elevation section of the whole line. The Xu-Hu line mainly passes through Huanghuai and Yangtze River Delta Plain, and partially (Bengbu-Danyang) passes through terraces, ridges and hills. The engineering geological conditions along the line are mainly soft soil and soft soil, which are widely distributed, especially the soft soil from Wuqing to Cangzhou and the soft soil from Danyang to Shanghai. The buried depth changes greatly, the soft soil layer is thick, the strength is low and the engineering properties are poor. The designed maximum running speed is 350km/h, the initial running speed is 300km/h, and the minimum train tracking interval is 3 minutes. It is estimated that after the completion of the Beijing-Shanghai high-speed railway, the train will run at a speed of 350km per hour, and the whole running time of Beijing South-Shanghai Hongqiao Railway Station will be 3 hours and 58 minutes. Run at a speed of 300km/h for 4 hours and 37 minutes; Run at a speed of 200km/h for 6 hours and 52 minutes. The annual two-way passenger transport capacity reached 65.438+0.6 billion passengers.

Railway route planning

The line is generally parallel to the existing beijing-shanghai railway, and the total length of the main line is about 13 18km, which is about 140km shorter than the existing Beijing-Shanghai line. The line leads from the west end of Beijing South Railway Station, along the existing Jingshan Line, passes through the newly-built Garden Station in Tianjin, and is connected with Tianjin West Railway Station through the tie line. Go south along the Beijing-Shanghai Expressway, cross the Yellow River 3 kilometers downstream of the Yellow River Bridge on the Beijing-Shanghai Expressway, and set up a new Jinan Expressway Station on the west side of Jinan City; Along the southbound east side of Beijing-Fuzhou Expressway, a new Xuzhou Expressway Station will be established in the east of Xuzhou City. At the downstream of the newly-built Huaihe Railway Bridge in Bengbu 1.2km, a new Bengbu station crossing the Huaihe River will be built, crossing the Chuhe River, crossing the Yangtze River with a victory of 20km upstream of the Nanjing Yangtze River Bridge, and then building Nanjing South Station, reaching Zhenjiang, Changzhou, Wuxi and Suzhou in the east longitude, and finally reaching Shanghai Hongqiao Railway Station. Tianjin, Jinan, Xuzhou, Bengbu, Nanjing, Shanghai and other hub areas will introduce existing stations by building tie lines.
