Wuhan railway authorities said that at present, Wuchang to Chongqing North K1024 / 1 train line passing through the Han Dan, Xiangyu Line, the whole 1226 km, takes 18 hours and 58 minutes. Starting January 11 next year, the change to go long trips Jing line, should million lines, the number reduced to 1136 km km, takes about 17 hours 6 minutes,karen millen dresses, only shorter than the current one hour 52 minutes.
why the construction of the most difficult
Wanzhou Railway is safe
According to reports, Wanzhou Railway's Yangtze River and tributaries, the mountains eroded into numerous deep canyons. Surface under water millions of years after the dissolution, the development of numerous caves and underground river systems strange, this is a blend of the natural wonders of heaven, God's wonderful creation picture, but in this region lay-step construction Step beholder, too easy, the underground river in the gushing water would roar out;'d been in the cave layers of rock will collapse.

Huzi Ping explained the program along the north shore of the Yangtze River has several major drawbacks: First, the line the same complex topographic and geologic conditions, construction difficulties; second, mostly along the remote town obvious pull on the surrounding urban economy ; Third destroy the Yangtze River and Qing River body is not conducive to environmental protection. Therefore, a comprehensive comparison of the
is line length of 377 km of the Yichang-Wanzhou Railway, Yichang, Hubei Province, east,ferregamo shoes, west Chongqing Wanzhou District. Started across the board from 2004 to the present was opened to traffic, the railway builders consumes 50,000 seven years, annual progress only 50 kilometers, is China's longest single-km railway construction. What are the reasons, so that the railway took so long?


Wanzhou Railway is located in the Yunnan-Guizhou Plateau and the Yangtze River Plain region of the junction, topography, geological conditions are complex. Then, run in such a complex geological region, Wanzhou Railway ride is safe? Upon completion, the experts have been divided into six groups on the hidden dangers that may exist along a number of intensive investigation.

why the Yichang-Wanzhou Railway not Among them, the Yichang section of 288 km east to cool mist for two, the design speed of 160 km; cool mist to Wanzhou section of 89 km for the single,gucci jewelery 直击：浙江兰溪遭受56年来最大洪峰, the design speed of 120 km. Prevalent in today's high-speed railway, Wanzhou Railway why not
Huzi Ping explained mainly used for high-speed railway passenger line, to build more in the economic conditions are good, the existing railway network density. The Wanzhou Railway lines are mixed passenger and freight transport. Along the town is not intensive, economy is not developed, the population is relatively sparse, economical use of existing standards can meet the actual needs.

two years to get through

Huzi Ping said: for the double-track. The early 1960s, Mao Zedong, Zhou Enlai and other leaders have planned construction of the older generation of Han River Railway, the choice is along the program. From the early days of New China Represented to the older generation of railway workers, although they have dreams, but the accumulated experience and information is still valuable. So, why give up the Yichang-Wanzhou railway line early design, while the

Wanzhou Railway level of risk, scale and difficulty of dealing with projects for domestic and foreign rare, especially in karst tunnel problems, a number of academicians and experts to be called the engineering world-class problems. For example, nearly 1,500 meters above sea level Qiyueshan, looks green and beautiful, but the construction of the tunnel in which clouds are dangerous. Qiyueshan tunnels have been discovered in the construction of melting chamber 150, surrounded by three river systems, various types of doline, shafts, sinkholes, riding point spread. Here groundwater rich, high pressure, flow, once released, can be easily sprayed hundreds of story building. Since the start of the tunnel pumping 63 million cubic meters, equivalent to taking away a large reservoir. The tunnel took nearly five years to promote more than 3,000 meters, to create their own
experts, many of Wanzhou Railway transport safety research and process design are a national initiative, part of the topic in the international technological frontier.








Wuhan - Chengdu T250 / 1 second, the current passing through the Han Dan, Xiang Yu, reached a line, the whole 1369 km, to be 18 hours 36 minutes. Starting January 11 next year, the change to go long trips Jing line, should million lines, up to million lines, the mileage down to 1268 km, but it requires 19 full hours and 25 minutes,versace sunglasses men, than the original but also to extend the 49 minutes.

Wanzhou Railway opened to traffic in operation today. This railway project is difficult because of its long construction period, and is widely attention. Why Wanzhou Railway known as the history of the most difficult railway construction? Why give up late Qing technical staff Prevalent in today's high-speed rail, why not Wanzhou Railway Complex geology along the railway, train safe? Iron four homes, several railway experts focus on community issues answered.

Shanghai-Wuhan-Chengdu large channel

Wanzhou railway opened, the correspondent from the Yichang-Wanzhou railway diagram found in Wuhan to Chongqing did not shorten the time, still need 18 hours. Prior to this, the relevant department, said, Wanzhou Railway opened, Wuhan to Chongqing, Chengdu, time will be significantly reduced. Why the time but almost no change?


example, in response to complex geology, the use of aerial photography and global positioning system (GPS) application of the latest technology - real-time dynamic positioning, large scale aerial photography and other advanced technologies; using ultrasonic technology to detect physical detection of deep underground rock properties. Through advanced measurement and exploration methods, identification of the basic control circuit program landslides, river and other major projects, hydro-geology and tunnel construction safety issues affecting geological disasters and complex geological background, the formation of law and control factors.

Wuhan railway authorities said that as long Wuhan to Yichang railway Jing is currently single, and the line quality is not high, only 60 kilometers per hour. The cool mist to the Yichang-Wanzhou Wanzhou Railway of 88.54 kilometers, is one-way design, the maximum speed of only 120 km, Wanzhou to Chongqing, Wanzhou to Chengdu railway speed is not high, therefore, subject to both ends of the rail speed limit, resulting in Wuhan to Chongqing did not speed.

railway department, Han-Yi next year after the opening of the railway, from Wuhan to Yichang from the current five hours to a half hour. Icheon to Chongqing Yu Lee after the opening of the railway in 2012,salvatore feragamo, the Shanghai-Wuhan-Chengdu Railway tunnel will be completely open, 5 hours to arrive from Wuhan to Chongqing. Chengdu to Shanghai region can achieve Zhaofaxizhi,
in the tunnel construction,ralph lauren clothes, carried out under high pressure conditions, type of supporting structure and construction methods, research, appropriate construction of the smooth development of million lines provide technical support. For example, for the tunnel through the large cave, engineers used the 26 reinforced concrete columns to be fixed around the cave, and in the cave of the upper two-tier framework for building the structure to stabilize the lining of the cave, it's like in the cave at the top is installed ceiling, Therefore, when the train through the tunnel is safe.

Huzi Ping said, Wanzhou Railway was launched three programs were selected for comparison: the first is along the Qingjiang, from Yichang, the Enshi, Icheon to Wanzhou; along the Yangtze River is the second program, from Yichang, the Zigui, Fengjie to Wanzhou; third option is now to build the program - The Enshi, Icheon to Wanzhou. These three scenarios,sale ralph lauren, the most contentious is the latter two options.
