Taiwan, a major project which can be the Great Wall, the difficulty of the Qinghai-Tibet Railway comparable? The answer is that tunnel.
Taiwan, formerly known as Snow Mountain Tunnel Pinglin tunnel, the longest highway tunnel in Taiwan, located in the Chiang Wei-shui Freeway (the "National Road" on the 5th, also known as the Taipei-Ilan Expressway) between Pinglin to the first section of the city. Tunnel from the three independent components: pilot tunnel, westbound and eastbound, a total length of 12.9 km. Snow Mountain Tunnel is the second longest road tunnel in Asia, second only to the Xikang Expressway in Shaanxi Qinling King tunnel, while the road tunnel in the world, ranked No. 5. The high degree of difficulty of this tunnel, also included in the Encyclopedia Britannica. Tunnel on June 16, 2006 opening. Length of 12.9 km, period 13 years, spent 60 billion.
Snow Mountain Tunnel not only the two main tunnels, but also the middle of the pilot tunnel. The middle of two main tunnels, who has 28 horizontal rows contact the tunnel, eight car dealers access road, together with pump drainage system mining shafts, ventilation ducts (including the three ventilation stations, relay stations air three total 12 horizontal ventilation tunnel, six ventilation shaft, on the 1st with a horizontal exhaust ventilation shaft at the top of the tunnel), and so, a total of 58 groups large and small Changzhangduanduan tunnel, is the world's largest holes of Highway Tunnels.
Taiwan's achievement enough to form the most global economic power, but the mountainous terrain to rural and urban economies into two, making transportation of goods and services not only lengthy and costly. The most obvious separate urban and rural areas than in Taipei and Ilan adjacent coastal areas. To connect these two centers, Taiwan's engineers will begin a seemingly impossible task: the construction of tunnels cut through mountains, snow-capped mountains as high as 3500 meters, the mountain steep, loose rock fragile. This is the human struggle with the high mountains, the whole project took 15 years, have been killed. Geologists will use high-tech tools to unlock the secrets of snow mountain, tunnel engineers were using the world's largest tunnel boring machine excavation excavation. Length 12.9 km of mountain tunnels, though not the world's longest tunnel, but it is certainly the most difficult tunnel project, a test of human determination, perseverance and technology. "Building wonders: Taiwan Snow Mountain Tunnel" in order to record the international point of view this first road tunnel in Asia, through video, 3D animation and engineers explain the interview, the Snow Mountain Tunnel all the time of construction show in the Asian audience.
Snow Mountain Tunnel last 15 years, length of 12.9 km, was the world as "mission impossible", but so far have successfully opened 2 months and 6 days, is the world's No. 1 long highway tunnel holes. James Gibbons (James? Gibbons) also praised Snow's vast and difficult tunnel project, he said: "Taiwan Snow Mountain Tunnel is the world's No. 1 is not only a long tunnel with two holes, but also by Encyclopaedia Britannica as the difficulty of the world rarely seen in the tunnel project This is a very worthy subject matter coverage. "snow tunnel caused by the opening of the positive effects: the opening of 2 months, there have been more than two million times through traffic, estimated an annual savings of 1 billion yuan fuel costs, an annual reduction of 50000 tons of carbon dioxide emissions, and the future can be reduced more.
Taiwan Snow Mountain Tunnel was Discovery Channel's "wonder building" special reports, other well-known complexity of the world's most magnificent building, including the transformation of Seoul, Korea, to build the Beijing Olympics are the Great Wall, the Qinghai-Tibet Railway, and South Korea's high-speed rail.
