From beijing to lhasa

  1. 1. From Beijing to LhasaChina’s Railway Across the Roofof the WorldBy www.ChinaTibetTrain.Com
  2. 2. • Since the founding of the Republic of China by Mr.Mao Ze ong in1949, it has been Chinas dream to have a railway to connect China Mainland and Tibet.• Tibet Highland is the last area to remain unconnected owing to great and insurmountable obstacles. Since the 1950s, among themany challenge facing Chinese railway planners, the following were the most significant.>> Formidable mountain barriers>> Unstable permafrost& swampy wetlands>> A Fragile
  3. 3. www.ChinaTibetTrain.comKunlun Mountain RangeTibet is Mother of Thousands of Mountains, mountain range that divides Tibet from the restof China, how the rail builders can guarantee that a train to Lhasa, which China has dreamedof since the 1950s. About 85 percent of the entire rail track is located in the forbidden zone.this is also known as the Death Zone, because of the air, harsh and unpredictable weather.Fierce sandstorms and high UV radiation. Annual average temp is minus Zero. Temp drops aslow as -45 degrees C. Average altitude of rail track here is 13500 feet above the sea level. thehighest point 16,700 feet making it the worlds most elevated track.When construction the Fenghuo Mountain Tunnel - 16,000 it above sea Level - workers had tobe equipped with oxygen cylinders. An Oxygen-producing station to "feed “the tunnel wasbuilt. Seventeen such station were built along the railway line equipped with high-pressureoxygen cabins for workers to recover.Question?How do you build a railway across these high mountains to Chinas most remote place, Tibet?

  5. 5. Unstable PermafrostThere is a total of 550km of permafrost along the rail route. Permafrost is soft and wet soil insummer, hard and expanding in winter – a nightmare for all railroad engineers.The most viable solution is the building of stone embamements for the railroad foundation. Insome places. Engineer bury ventilation pipes in the ground to allow cold air to circulateunderneath the rail-bed.In other spots, a pipe called a thermosiphon is sunk 15 feet into the ground and filled at thebottom with ammonia. The ammonia becomes gas at low temperatures. Giving off a vapourthat draws heat from the bottom with ammonia. The ammonia becomes gas at lowtemperatures. Giving off a vapor that draw heat the bottom of the tube and flushes it out thetop.Building a bridge over the permafrost. This has the least impact on the rea. But is also th mostexpensive. Eg. The 11.7 km Qingshuihe Bridge is the world-longest Bridget buit on permafrost.A round-the-clock monitoring system bas been installed to keep tab on the temperaturechange along the 550km permafrost stretch of the
