解惑“metcn—HDvideo”-环球时报

三跨天山,要经历metcn—HDvideo多少难关?

最佳回答

“metcn—HDvideo”三跨天山,要经历metcn—HDvideo多少难关?

  天山metcn—HDvideo其实不是一座山,而是由三条山metcn—HDvideo脉和众多山中盆地组成的超级山系,它绵延2500多千米,横亘中国新疆,并延伸到中亚地区。险峻地形和多变气候造成的交通不畅,不仅影响游客的出行体验,更掣肘着南北疆交流和经济协同发展。在堪称中国公路地质灾害博物馆的天山修建安全快速还能全年通行的道路,中国工程师要面对哪几道难关?

  大西洋和北冰洋泛起的高空水汽穿过欧亚大陆,抵达天山后,便被冰封在天山雪线以上,形成了万年不化的冰川。在冰川下修建隧道,工程师无法用传统的竖井方案解决通风问题。他们要如何创新,才能让冰川保护和隧道通风二者兼顾?

  岩爆,是修建隧道时山体释放压力的一种形式,也是工程师谈虎色变的一个词语。在有极高岩爆风险的天山掘进隧道,工程师如何给掘进机设计护甲,抵御岩爆给施工人员和设备带来的风险?

  只有200万年历史的天山深处却潜藏着地球3亿年前的古老伤痕。博阿断裂带,横贯整个天山山脉,断裂最深处超过30千米,已经撕裂地壳直达地幔。面对断裂给隧道施工带来的地震风险,工程师如何改变传统设计思路以柔克刚?隧道内大量涌水,又怎么实现层层净化,保护重要的水源地?

  为将工程建设对植被的影响降到最低,工程师需要在施工的同时,用补种植物的方式修复生态。如何选择植物才能保护天山脆弱的生态圈?那些穿山越岭的隧道大桥,在给你我带来便捷交通的同时,又能为天山的万物生灵提供哪些保护?

  超长隧道,水多天冷,在天山修建隧道面临大量影响隧道畅通的不利因素,工程师将用怎样的手段破解难题,保障隧道贯通后交通通畅?借助数字化改造传统基础设施,又能给天山隧道畅通增加哪些保障?

  三条跨越天山的隧道,虽然深藏于幽远之中,通向的却是灿烂的光明。因为中国的工程人从来不会只着眼于当下,他们的心中有星辰大海,打通的隧道不仅会跨越天山,在实践中不断积累的绿色技术、数智技术更可以集合成中国交通建设领域新质生产力,在难度更大、生态更敏感的地方,逢山开路,遇水架桥,挑战人类交通工程的极限巅峰。

  交通运输的高质量发展,使路网由大写意变为工笔画,让边疆地区在走向共同富裕的道路上不掉队;让各族人民实实在在感受到推进共同富裕在行动、在身边,让美好生活惠及每一处边远的地方。
