57 km! Most tunnels in Switzerland officially opened-the world's most long-IT information
According to the BBC report, the world's longest train tunnel most recently in Switzerland officially opened. After 20 years of construction, the line through the Alps, length of 57 km twin bore tunnel 2.3 meters deep--Gotthard infrastructure announced completion of the tunnel. It will connect southern and Northern Europe, for European freight brought a new revolution.
After the opening of the Gotthard, will surpass Japan Seikan tunnel, the longest tunnel in the world while connecting the English Channel tunnel between Britain and France was third. North of the tunnel to Switzerland Uri Erstfeld in Central, South to Ticino Baudiot invested 12 billion Swiss francs to build, using a life span of 100 years.
Foreign media, citing Switzerland Federal President John Schneider-Oman at the launching ceremony of the tunnel as saying: "this is not only Switzerland, but also our neighbours, as well as the continent's victory. "Germany Chancellor Angela Merkel, France President Francois hollande, and Italy Prime Minister, Renzi and other European Heads of State participated in the opening of the Gotthard. After the ceremony, tunnel operating service for the first time, 500 won by lot travel passengers lucky enough to be among the first to experience for the first time.
This open Europe's North-South rail tunnel idea going back to 1947. Switzerland engineer Gruner describes design sketches of the Gotthard Base Tunnel, but due to the delays in approving projects until 1992, when the project was approved, 1999 he didn't start, finished in 17.
Public information, tunnels will be officially began commercial operations in December of this year. When the daily would have 260 trucks and 65 passenger train cross the double holes tunnel. After the tunnel from Switzerland Zurich to Italy Milan trip will be shortened to 1 hour to 2 hours and 40 minutes. By 2020, passenger cars will reach 15,000 passengers.
However, Gotthard world record how long is a question. Because it may soon be overtaken by a more ambitious programme of cross-harbour tunnel. China is planning to build a more than 123 km long, crossing the Bohai Sea-crossing the cross harbour tunnel smoke tunnels. The tunnel will connect Dalian and Yantai, calculates with train speed of 220 kilometers, after the completion of the tunnel just 40 minutes from Penglai to Lushun, than is currently over 6 hours between the time is considerably reduced. But there is news that is similar to the Thomas g build Hyperloop vacuum trains may also be a common tool in the future. If the rumors are true, then from Yantai to Dalian took only 12 minutes of access time.
Public information after the vacuum trains Beijing Jiuzhou artery tunnel design company chairman Liu Zizhong was held in April this year in Yantai of the Bohai Sea Straits, spanning sea channel and the seminar on the national strategy for regional development, introduced in public train: "get a pipe into the seabed, water out of it, put people in a capsule inside the train. "Bohai Sea tunnel initiator, ludong University former Vice President Liu Xinhua has studied the subject for 20 years, he said:" Penglai, Yantai to Dalian Lushun only 106 kilometres distance, you now need to pass more than 1800 km, was wondering how broken growth biggest bottlenecks of traffic restriction, Yantai, Yantai as an international city. ”
Yan-da tunnel research on strategic planning of the project team, the Chinese Academy of engineering Academician Wang mengshu told media that the total cost of the project in 2000 to about 260 billion yuan between. However, the project still debate whether conditions are mature. Wang mengshu, said: "the project in 2013, reported to the national development and Reform Commission. Has not yet commenced, the main challenge is the rigorous exploration and demonstration. Under current terms, within 10 years after the start of the project to complete. ”
The coincidence is, super high-speed Hyperloop One Global CEO Rob Lloyd last month came to China, his first financial reporters "by 2017, Hyperloop high-speed trains will be put into commercial use, hopes to gradually arrive anywhere in the world, the company has been in the United States, Northern Europe and Russia and other countries for project assessment and hope that it will greatly reduce the cost of high-speed trains. "Lloyd also said that coming to China for China's ambitious rail-building interest. But how to make better collaborative Government, technology and capital, the biggest challenge is to achieve high-speed operation.
57公里！全球最长隧道在瑞士正式开通 - 全球最长隧道 - IT资讯
据BBC报道，全球最长最深的火车隧道日前在瑞士正式开通。经过长达20年的建设，这条贯穿阿尔卑斯山，全长57公里、深2.3米的双孔隧道——圣哥达基建隧道宣告完工。它将连接南欧和北欧，为欧洲货运带来一场新的革命。
圣哥达隧道开通后，将超过日本青函隧道，成为世界最长的隧道，而连接英法之间的英吉利海峡隧道位列第三。该隧道北至瑞士中部乌里州的埃斯特费尔德，南至提契诺州的博迪奥，投资120亿瑞士法郎建造，使用年限为100年。
外媒援引瑞士联邦总统约翰-施耐德-阿曼在隧道启动仪式上的话说：“这不仅是瑞士，也是我们的邻国以及欧洲大陆的胜利。”德国总理默克尔、法国总统奥朗德、意大利总理伦齐等多位欧洲国家元首参与了圣哥达隧道的开通仪式。仪式结束后，隧道进行首次通车运营，500名通过抽签赢得首次旅行机会的乘客有幸成为第一批体验者。
造这样一条打通欧洲南北的火车隧道的想法最早要追溯到1947年。当时瑞士工程师格鲁纳就描绘出圣哥达基线隧道的设计草图，但由于工程审批的拖延，直到1992年这项工程才获批，1999年才开始动工，于17年后完成。
公开资料显示，隧道将于今年12月正式开始商业运营。届时每天将有260列货车和65列客车穿越这条双孔隧道。有了这条隧道后，从瑞士苏黎世到意大利米兰的行程将缩短1小时至2小时40分钟。到2020年，日载客辆将达到1.5万人次。
不过，圣哥达隧道全球第一的纪录能保持多久是个问题。因为它或许很快就会被一项更为雄心勃勃的海底隧道计划所超越。中国正在筹划建设一条长超过123公里，穿越渤海的跨海海底隧道烟大隧道。该隧道将连接烟台和大连，以火车220公里的运行速度来计算，隧道建成后从蓬莱至旅顺仅需40分钟，比目前来往两地时间超过6小时的时间大大缩短。不过也有消息称类似于马斯克打造的Hyperloop真空列车也有可能成为未来的一种通行工具。如果传言属实，那么从烟台到大连的通行时间仅花费12分钟。
公开资料显示，此前中国真空列车设计公司北京九州动脉隧道有限公司董事长刘子忠在今年4月于烟台召开的渤海海峡跨海通道与国家区域发展战略研讨会上，公开介绍了真空列车：“就是把一根水管塞进海底，把水抽出来，把人装进胶囊列车里面。”渤海海底跨海隧道发起者，鲁东大学原副校长柳新华研究该课题已有20年，他说：“烟台蓬莱到大连旅顺直线距离只有106公里，现在需要绕道1800多公里，当时就在想如何打破烟台成长发展交通制约的最大瓶颈，让烟台成为一个国际型的城市。”
烟大海底隧道战略规划研究项目组组长、中国工程院院士王梦恕曾对媒体表示，该工程的总造价大约在2000至2600亿元人民币之间。不过这一项目建设条件是否成熟的争论仍然存在。王梦恕说：“该项目2013年上报国家发改委。目前尚未动工，主要的挑战是严格的勘探和技术论证。按照当前的条件，项目开工后10年内肯定能够建成。”
巧合的是，上个月超级高铁Hyperloop One全球CEO Rob Lloyd来到中国，他对第一财经记者表示：“到2017年，Hyperloop的高速列车将投入商用，希望逐步抵达全球任何地方，公司已经在美国、北欧以及俄罗斯等国进行项目评估，希望将把高速列车的成本大大降低。”Lloyd还表示，来到中国也是对中国雄心勃勃的铁路建设充满兴趣。不过如何让政府、技术和资本三者更好地协同，是实现高速铁路投入运营的最大挑战。
