5年前,苍凉广袤的青藏高原上响起了铁路开工的号令,经过铁路建设者们5年的艰苦施工,终于建成了这条世界最长的高原铁路。在号称“地球第三极”的青藏高原上,青藏铁路无疑是条神奇的“天路”,它的建设要克服“多年冻土、高寒缺氧和生态脆弱”三大世界性难题,要穿过长550公里的高原冻土地带,凿通世界最长的高原冻土隧道全长1686米的昆仑山隧道;跨越5072米高的唐古拉山口以及长965公里、海拔4000米以上的地区;深入可可西里自然保护区……青藏铁路无疑是世界上最壮观的铁路之一,它创下了多项“中国之最”、“世界之最”和“历史之最”。
Five years ago, the command of starting the railway started on the desolate and vast Qinghai-Tibet Plateau. After five years of hard construction by railway builders, it finally built the longest plateau railway in the world. On the Qinghai-Tibet Plateau, known as the “third planet of the earth,” the Qinghai-Tibet Railway is undoubtedly a magical “heavenly road.” Its construction needs to overcome the three global problems of “permafrost, anoxia, hypoxia and ecological fragility.” 550 km long plateau permafrost, cut through the world’s longest plateau permafrost tunnel length of 1686 meters of Kunlun Mountain Tunnel; over 5072 meters high Tanggula and 965 km long, more than 4000 meters above sea level; depth of Hoh Xil Nature Reserve ... The Qinghai-Tibet Railway is undoubtedly one of the most spectacular railroads in the world. It has set the number of “most in China”, “the highest in the world” and “the highest in history” in the world.
