2月16日，农历除夕。早晨7点多，记者来到洛阳市孟津区送庄镇后沟村旁的邙山隧道施工现场。远远望 去，"邙山隧道"的红色横幅在晨光中格外醒目，几名身着橙色工装的建设者身影，打破了工地的宁静。 "脚步轻一点，别碰着监测仪导线。"刚走进隧道洞口，就听见测量员王浩压低声音叮嘱。他身着沾满尘 土的工装，安全帽上的矿灯还亮着微光，手里紧紧攥着监测仪器，正弯腰对隧道围岩进行细致量测。冰 冷的仪器贴在隧道岩壁上，他的指尖冻得发红，却依旧稳稳把控着操作节奏，目光锁定仪器屏幕上跳动 的数字。 王浩有着10年施工经验，负责隧道围岩监控量测工作。"我们的核心任务，就是实时紧盯隧道沉降和岩 土收敛情况，这是隧道安全的'晴雨表'。"他指着仪器上的数值解释，一旦沉降超标，就意味着土层可 能不稳定，必须立即上报并采取支护措施。 邙山隧道作为焦济洛平高铁的控制性工程，与洛阳黄河公铁两用大桥共同构成全线"咽喉"节点，自北向 南穿越邙山屏障，全长6340.06米，是全线最长隧道，更是目前世界上开挖断面最大的土压平衡大盾构 高铁隧道，施工技术与工程规模均处于行业领先水平。 这里地质条件复杂，以Ⅴ级围岩黄土地质为主，最大埋深约40米，属于浅埋黄土隧道 ...

Group 1 - The construction of the Mianshan Tunnel, a key project of the Jiaoluo-Ping High-Speed Railway, has successfully completed the shield starting well's diaphragm wall construction, marking the acceleration of the world's largest diameter earth pressure balance shield tunnel construction [1] - The Mianshan Tunnel, the longest section of the Jiaoluo-Ping High-Speed Railway at 6340 meters, is being constructed using a shield method, setting a world record for the excavation cross-section size of earth pressure balance shield tunnels [1] - The project team has innovatively adopted a composite cyclic slotting scheme to address challenges posed by complex geological conditions, ensuring safety and quality while effectively advancing construction progress [1] Group 2 - The Jiaoluo-Ping High-Speed Railway spans 230 kilometers with a design speed of 350 kilometers per hour, forming an important part of China's "Eight Vertical and Eight Horizontal" high-speed rail network [2] - Upon completion, the railway will enhance the hub function of the Hunan-Guangdong corridor, enabling a one-hour travel time between Jiaozuo and Pingdingshan, which will promote regional industrial collaboration and resource sharing [2]
