这是一段关于人类征服自然、开创宏伟工程的史诗。
影片开篇，一道象征着探求与突破的蓝色光束，从冰雪覆盖的山巅直插云霄，仿佛要刺穿地球的深邃。随后，画面切换至地球的剖面图，展现了马里亚纳海沟的深度以及地球地壳的厚度，数字“22.1km”和“17km”赫然醒目，暗示着即将面临的挑战，其难度堪比贯穿地心。
紧接着，镜头从宏大的地球视角拉回人间，一列极氪001轿车行驶在蜿蜒曲折的山路和明亮的隧道中，预示着这段旅程的目的地——新疆乌尉高速。这是一条连接乌鲁木齐与库尔勒的重要动脉，但其穿越天山的道路，却充满了艰险。
“打穿天山，有多难？”字幕打出，揭示了影片的核心主题。画面随即展现了天山山脉的雄伟与险峻，雪峰连绵，谷深路窄。其中，老虎口路段以其盘旋陡峭的国道216线，成为过去连接南北疆的咽喉，但通行效率低下。地图对比显示，绕行G30和G3012的大环线长达470公里，而直接穿越天山的路线只有340公里，节约了巨大的时间和距离。
工程师们经过反复勘测，最终确定了穿越天山的“中线”方案，隧道洞口海拔高达3217米。这是一个前所未有的挑战，首先要面对的是复杂的岩石地质。传统钻爆法和斜井、横洞的辅助方法都在考虑之列。
随后，画面聚焦于一项现代工程奇迹——硬岩掘进机（TBM）。它巨大的刀盘和强劲的撑靴，成为人类开凿山体的利器。我们看到TBM在黑暗的隧洞中轰鸣推进，碎石飞溅，尘土弥漫。工人们在狭窄、潮湿的环境中，夜以继日地奋斗。主洞直径7米，TBM直径6.56米，每一寸的开挖都凝聚着汗水与智慧。经过52个月的艰苦卓绝，这条隧道预计在2024年12月30日成功贯通。
然而，挑战远不止于此。“地质太复杂了！”影片进入第二关。花岗斑岩、变砂岩、板岩、大理岩，各种复杂岩层交织，甚至还要穿越460米宽的博罗科努-阿其克库杜克活动断裂带。地下水如瀑布般倾泻而下，施工人员在泥水中艰难前行。为了应对这些恶劣条件，TBM配备了盾构模式和多种支撑技术，如钢模板、混凝土和钢管片，以适应不同的地质结构。甚至在极端复杂的地段，工程师们还设计了迂回导洞，展现了灵活应变的智慧。
第三个难关是“通风太难了！”漫长而深入地底的隧道，通风是保障施工和未来运营的关键。画面展示了巨大的风机房和密集的通风竖井网络。其中，2号竖井深度达到707米，比上海中心大厦还要高，堪称世界级的垂直工程。为了开挖这些深井，中国自主研发的“首创号”竖向掘进机应运而生，其11.4米的巨大刀盘，犹如钻头巨兽，自上而下地凿穿岩层。
最后一道挑战是“温度太低了！”天山地区常年严寒，冰雪覆盖。极氪001轿车再次出现在冰天雪地的公路上，展示其900V三电技术和PTM2.0全域热管理系统，能够从容应对极寒环境，这既是车辆的性能展示，也隐喻着隧道工程对极端气候的克服。在隧道的深处，画面展示了地热换热管路和废水处理厂，体现了工程对环境保护和可持续发展的重视。
随着地形测量的画面，隧道内部的壁画映入眼帘，蓝天白云、雪山戈壁，将外部的壮丽景色带入地下，减轻了驾驶者的视觉疲劳，也彰显了人性化的设计。
影片最后，一幅由高速公路和国道构成的中国交通网络图徐徐展开，特别是新疆地区的密集路网，如同一条条连接东西的现代丝绸之路。历史的画面闪回：张骞出使西域，开辟丝绸之路；15世纪海陆贸易兴起。再到现代：2023年中国（新疆）自由贸易试验区成立，2024年中欧班列运行突破10万列。这一切都与这条贯穿天山的隧道息息相关，它不仅缩短了距离，更打通了区域发展、国家繁荣的命脉。
极氪001车队穿梭于明亮的隧道中，字幕打出：“极氪偕装，第一时间见证祖国山河壮美。”这不仅是对汽车品牌的宣传，更是对这条伟大工程的礼赞，它让人们能够更快、更便捷地领略祖国的大好河山，也寓意着科技与工程的进步，共同推动着时代前行。
最终，滚动的演职员表和幕后花絮，向所有为这项“新天工开物”工程付出心血的建设者们致敬。这条隧道，是人类智慧与勇气的结晶，是现代科技与大自然的一次伟大对话。

This audio describes the construction process, technological innovations, and significant importance of the Tianshan Shengli Tunnel.
The main content is as follows:
1. **Tunnel Overview and Grand Goals:**
* The Tianshan Shengli Tunnel is 22.1 kilometers long, making it the world's longest highway tunnel.
* Its length is equivalent to going from the summit of Mount Everest to the deepest point of the ocean floor, or directly piercing through the Earth's crust.
* Located in Xinjiang, the tunnel is expected to be fully open to traffic on December 26, 2025.
* It marks the first time a highway will traverse the Tianshan Mountains, connecting northern and southern Xinjiang.
2. **Construction Background and Challenges:**
* Historically, traffic across the Tianshan Mountains relied on the "Tiger's Mouth," a pass blasted open manually over 60 years ago, but the winding mountain roads were time-consuming and dangerous.
* The straight-line distance from Urumqi to Korla is 250 kilometers, but the detour requires 400 kilometers and takes 7 hours.
* Directly crossing the Tianshan Mountains is a faster option, but selecting the tunnel location was difficult (too low would make it too long, too high would still involve steep climbs and snow accumulation).
* Therefore, the final choice was to build a 22.1-kilometer tunnel, which is 4 kilometers longer than China's previous longest tunnel, the Zhongnanshan Tunnel.
3. **Major Construction Challenges and Innovative Solutions:**
* **Challenge One: Long Construction Period**
* Traditional drilling and blasting methods would take over ten years, and even with auxiliary tunnels, it would require 72 months.
* **Solution:** Innovatively adopted the "long tunnel, ultra-short construction" strategy, constructing a pilot tunnel (parallel adit) in advance between the two main tunnels.
* The pilot tunnel divided the entire tunnel into 15 sections, with up to 14 working faces operating simultaneously during peak periods.
* For this purpose, China's independently developed "Tianshan" and "Shengli" TBMs (Tunnel Boring Machines) were used. With a cutterhead diameter of 8.43 meters, their excavation speed is 3 to 10 times faster than traditional methods, prioritizing the rapid excavation of the pilot tunnel.
* The main tunnels, with a diameter of 14 meters, were constructed using traditional drilling and blasting methods. The tunnel was finally holed through in 152 months.
* **Challenge Two: Complex Geology**
* The Tianshan Mountains have fractured rock masses, with 10 different types of rock and 17 fault zones, the largest of which, the Uwa Fault Zone, is 460 meters wide.
* Traditional TBMs struggle with the uneven, soft and hard, and variable fractured geological conditions.
* **Solution:** Unprecedented upgrades were made to the "Tianshan" and "Shengli" TBMs.
* In hard rock layers, conventional mode was used; in softer, fractured rock, steel formwork was first erected, then concrete was poured to stabilize the tunnel body; in extremely deformable and fractured "hell mode," stronger steel trusses were used for support, similar to a shield machine.
* In case of machine jamming, the pilot tunnel could be used to bypass from the main tunnel route to the front of the cutterhead for emergency rescue.
* The main tunnels adopted a "softness overcomes hardness" solution: foam concrete was filled into nearly 40,000 PE pipes, wrapped around the tunnel walls to form a 70-centimeter-thick shock-absorbing layer; and "tendon-type" expansion joints, 1 meter wide, were left every 30+ meters in the reinforced concrete lining, making the tunnel structure flexible like a multi-section staff, significantly reducing the impact of fault displacement.
* **Challenge Three: Ventilation Difficulties**
* For such a long tunnel, fans can only directly supply air for a maximum distance of 5 kilometers.
* **Solution:** Four ventilation shafts were excavated from the mountaintop down, connecting the two main tunnels.
* The 22.1-kilometer tunnel was divided into 5 sections for ventilation, with the deepest shaft reaching 707 meters.
* **Innovative Technology:** The world's first hard rock vertical boring machine, "Shuchuang," was used. It combines TBM and oil drilling technology, capable of directly drilling vertical shafts 11.4 meters in diameter to great depths, and operates unmanned.
* **Challenge Four: Low Temperatures and Extreme Cold**
* The tunnel portal is at an altitude of about 3,000 meters, with an average annual temperature of -5.4°C and a minimum reaching -40°C.
* Without cold protection and insulation, ice could form, affecting traffic and even damaging the structure.
* **Solution:** Not only was insulation added, but heating systems were also installed inside the tunnel.
* Utilizing the constant geothermal temperature inside the mountain as a heat source, stable heating is achieved through heat exchange pipes laid within the tunnel lining.
4. **Additional Challenges and Comprehensive Benefits:**
* Constructors also had to address challenges such as waste slag and wastewater treatment, ecological and environmental protection, geological surveys, emergency rescue, and fire prevention.
* After the Tianshan Highway opens, the drive from Urumqi to Korla will be shortened from 7 hours to about 3 hours.
* Combined with the Duku Highway and Zhaowen Highway, Xinjiang will have a comprehensive highway network extending in all directions.
* In the future, traveling eastward over 3,000 kilometers from Xinjiang will reach any city in China, and traveling westward over 3,000 kilometers will reach any country in Central Asia.
5. **History and Future Prospects:**
* This important route, which flourished for a thousand years after the Han Dynasty, gradually faded from the center stage after the Song Dynasty. Now, it finally has the opportunity to regain its former glory.
