One of the Innovation Team winners in this year’s China National Science and Technology Awards is a team that has been researching construction on permafrost for almost half a century and made the completion of Qinghai-Tibet Railway possible in 2006.

For the railway on the world's highest plateau, the biggest challenge was the unstable terrain of permafrost. One of the people who solved that problem was Cheng Guodong.

Since graduating in the 1960s, Cheng has been following his predecessors and researching permafrost. The development of the railway line went through twists and turns, but he never gave up.

Cheng's research focuses on infrastructure construction projects in regions which have permafrost, such as the building of railways and highways. It's quite a complex line of work for his team.

The construction of the Qinghai-Tibet Railway started in 1958. Despite the permafrost, the ground on the surface of the plateau does melt, with the ground expanding when it freezes and turning into slush when it thaws. This threatens to deform and destroy any construction built on it, including the railway, so the roadbed soils need to be kept frozen.

According to Cheng, there are three major ways to keep permafrost stable, namely regulating the radiation, the convection or conduction patterns of heat.

Cheng said they used many ways to increase efficiency that were environmentally-friendly, low-cost, and easy to adopt, and they constantly made changes due to new conditions.

More projects are planned for the plateau, including an expressway and an oil pipeline. And knowledge gleaned from a surprising discovery just 200 kilometers from Beijing will help.

Niu Fujun, a member of Cheng’s team said they recently went out for a study in Chengde in north China's Hebei Province, and unexpectedly discovered permafrost only two meters below ground level.

The means annual air temperature there is 7.8 degrees Celsius. So they made comparisons to the conditions of the permafrost under the railway on the plateau.

Research is needed to make sure the cooling system for the Qinghai-Tibet Railway works even when temperatures rise due to global warming.

And their mission goes beyond that. A new railway linking China and Russia has also been added to the agenda.

"If the railway is completed, a lot can be transported along it, but the regions it crosses are basically frozen," said Cheng.

To complete this railway, which is intended to cross Asia and Europe, the team is expanding its cooperation with other countries and will hold an International Conference on Permafrost in 2020.

Cheng said he is glad his team won a national award, and he hopes more funds will be given to scientists, especially those in China's vast western regions.

Do you know which railway will open after Chongqing-Guiyang Railway?

250km/h freight cars for High-speed Railway
In test

Woman (a teacher) blocked bullet train door to wait for her husband
(Technically once the door is blocked, there is no way trains can proceed)
Train departure was late for 4 minutes.
Woman was suspended by her school
Local education bureau press conference announced....


This woman was f***ing crazy.
She was an embarrassment to her husband, her family, her school....
It was so embarrassing that a department of education hold a press conference
just to say they felt sorry for the society.....they said it was first ever in the history of the education sector of the entire district.....

But thankfully, she was not in Murika.
If she were there, she would:
1, Nobody cares, becos punctuality is nothing;
2, If there is police around, she will got shot.

Anyway, shame on her.....
20+ million views on Weibo must have given her a big life lesson.
She should not just get suspended from her job, but she should be on the blacklist of public transport.

Sorry if I was out of topic, this incident should become lesson for public authority about safety and security in public service area. This footage show entirely about most debate with this crazy woman, where's the police or security in this place? She should arrested due obstruct public service, if there's ten to hundred people like her in the train. what the point building high-speed train? My point is security force must reacted fast to counter such issue.

Chinese police is not like that....
They don't even have weapons for the most of the time.
Dragging, fighting, or even using a gun.....probably not our options....
hence, she was suspended, though local district bureau of education might have nothing to do with it.

For punctuality....don't worry....
Even a bullet train leaves 10 minutes later, it will still arrive on time...
There is always some room.

But I got your point....

That's the way it is, i think. Like @AndrewJin says, police in China (Mainland as well as Taiwan) are extremely reserved to take harsh action.

I have watched the footage this morning on online CCTV4 broadcast again, can't believe the lady was even insisting to obstruct the door while the police was trying to persuade her to step aside.

Nonetheless, I think this is an outlier case and won't probably be repeated after she got so much bad public exposure.

Still, I like it more to see the police not to so easily resort to violence (pushing down, arresting etc.). China's public life is therefore much more peaceful and harmonious. Unlike in the US, one won't be scared seeing a policeman approach him/her.

Due to the human rights bashing on China, the police are extremely careful not to exert force. In the US, that women who have been brutally bashed up. This is the irony of things, the authoritarian being nice and the free and democratic abusing their citizens.

Before the inauguration of the new Chongqing-Guiyang Railway
opens 2 weeks later,
let's recall the old one!

In this photo, left to the old single-track railway we can see the construction
of the new railway (to open in 2 weeks)
On the right we see the new village road and an expressway....
The old railway was revolutionary when it was built in 1950s.
But it no longer serves today's need.

Old Chongqing-Guiyang Railway vs Expressway

If a railway is more curvier than a road, it means this railway is outdated.....
The old railway should be only for freight and village trains.
It is beautiful, but beauty does not mean productivity....

Boasting 3 world records! A new railway bridge over China's Yangtze to be completed soon
New China TV Published on Jan 11, 2018

The New Baishatuo Railway Bridge over China's Yangtze River is about to open to traffic. The bridge bags three world records.

The New Baishatuo Yangtze River railway bridge (upper) is seen with the previous Baishatuo Yangtze River railway bridge in Jiangjin of southwest China's Chongqing Municipality, Jan. 9, 2018. The construction of the new double decker steel truss cable stay railway bridge was finished recently. It has 4 tracks on the upper deck for passenger trains with a designed speed of 200 meters per hour and 2 tracks on the lower deck for cargo trains with the designed speed of 120 kilometers per hour. The overall length of the bridge is 5.32 kilometers, of which the main bridge is 920 meters. Together with the Chongqing-Guiyang railway, which is to be in operation, the bridge will undergo the test operation soon. (Xinhua/Liu Chan)

China's high-speed rail hit a new high mileage! 24,000 km continuing to rank first in the world

China Daily, December 27 (Reporter Tama Wang Shu) On Wednesday, Li Xiaopeng, Chinese Minister of Transportation, said at the national civil aviation work conference in 2018 that by the end of the year, the mileage of China's high-speed railways is expected to reach 24,000 km. The national railway mileage is expected to reach 126,000 kilometers.

At the end of last year, Yang Yudong, vice minister of China's Ministry of Transportation and the director of the National Railway Bureau, said that the mileage of China's railways has reached 124,000 kilometers, that of high-speed railways has reached more than 20,000 kilometers and that the mileage of operations accounts for 65% of the total high-speed railways in the world. about.
