Overview of Beijing Metro 10 Line

There are 84 trains on 10 line, which can basically meet the requirement that the departure interval of existing lines is 2 minutes and 30 seconds. It is learned from the municipal rail transit construction management company that the 10 line has realized the "O"-shaped track connection.

On May 5th, 20 13, the first bus of 10 line started to leave at Bagou Station, and 10 line finally changed from "C" to "O", becoming the second ring road of Beijing subway, and three stations of Jiaomen East, Niwa and Fengtai Station were opened at the same time. The total length of 10 line is 57. 1km, with 45 stations. It is the longest underground subway line in the world.

The first phase of 10 line was opened at a high level at intervals of 3 minutes for the first time in China. During the Olympic Games, 9.6 million passengers were safely transported, and the operation has been zero since its opening. Showed the world the advanced level of China urban rail transit construction.

The first phase line 10 has a total length of 24.65km, all of which are underground lines. Including 22 stations, 1 depot, and the control center is located in Xiaoying: the long-term daily traffic volume 165438+ 10,000 person-times, and the peak hour one-way maximum cross-section traffic volume is 40,000 person-times; Adopt the national standard B 1 six cars; The total investment of the project is about 1, 3 1 100 million yuan; Construction started in June 5438+February 2003, and was put into trial operation in July 65438+September 2008.

The second phase of 10 line was opened on February 30th, 20 12, in which the first economic and trade-West Bureau has a breakpoint, and the train runs back and forth from West Bureau to First Economic and Trade. Breakpoints (Niwa Station, Fengtai Station and Jiaomen East) are at 206544. The first phase project of 1 and 10 line is the transportation project that the country promises to hold the Olympic Games. It is the only line connecting Metro Line 8 (transfer at "Beitucheng" station) and other existing subway networks, and plays a key role in the Olympic traffic guarantee.

2. The first phase of10 line is a semicircle line, which forms an interchange with most completed subway lines and planned subway lines, which can not only reduce the pressure on the loop line (Line 2), but also make Beijing rail transit enter the network era.

3. The first phase of Line 1 0 passes through Zhongguancun, Olympic Park and Beijing Central Business District (CBD), and is interchanged with Line 4, No.8 Olympic Branch Line and Line1respectively, forming three golden crosses of rail transit, greatly improving traffic congestion in the above areas and promoting economic development. Most of these areas are located in the north city, which can be called Beijing subway network. Features: Serving the Olympic Games, there are many transfer points, forming a Beijing rail transit network.

Implementation features: the shortest construction period and the most difficult implementation.

Highlights of the project: adopting the world's most advanced operation control system; The highest level in the country is opened, and the running interval is 3 minutes; Full implementation of short-term and long-term transfer design; Thoughtful convenience service facilities; In Beijing, three new forms of stations were innovatively designed, namely, separated island type, 10m single column type and 8m non-column type. Decorative design with the characteristics of the times. Main design (and survey) units

Design objectives and principles:

Overall technical goal: to serve the Olympic Games with high quality; Improve the traffic conditions of Zhongguancun Science Park, Olympic Park and business center; Very suitable for the existing production line.

The planned lines have been transferred and connected, and the Beijing rail transit network has been improved;

Overall technical principles: people-oriented, green, safe and reliable, economical and practical, and high localization rate;

1, line, vehicle, operation:

(1) Line: The minimum curve radius is 350m, and the maximum gradient is 29‰.

(2) Vehicle: B 1 vehicle with domestic VVVF AC traction drive mode standard is adopted, and the upper part of DC750V contact rail receives electricity.

(3) Operation: The early, near and long-term trains consist of six three-car trains and three trailers. The train capacity is 1468, and the maximum traffic density in the long-term peak hours is 30 pairs/h. ..

2, civil engineering:

(1) Building: Island platform stations are mainly selected, and some side platform stations are adopted; The station construction adopts three ways: full open excavation, full underground excavation and combination of light and shade; The interval construction mainly adopts three construction methods: open excavation, underground excavation and shield.

(2) Structure: The designed service life of underground structure is 100 year, and the designed service life of above-ground structure is 50 years; The safety level of underground structure is Grade I, and the important coefficient y0 =1.1; +0; The design seismic intensity of this structure is 8 degrees.

(3) Civil air defense: the underground station and its adjacent sections are designed according to the requirements of 5-level segmented isolation protection for civil air defense, and the chemical protection level is top. Each unit is considered as a temporary shelter for 65,438+0,500 people in wartime.

3, equipment system:

(1) Track: No.9 straight-pointed fork of 60kg/m track is adopted for the main line, and No.7 curved-pointed fork of 50kg/m track is adopted for the depot; The short sleeper monolithic track bed shall be laid in general sections of the main line, and the steel spring floating plate monolithic track bed, in-yard monolithic track bed and out-of-yard gravel track bed shall be laid in special vibration reduction sections.
