长江日报讯（记者汪文汉 通讯员许豹 黄子珅）6月13日，由湖北交投集团投资、中交 二航局承建的武汉双柳长江大桥项目主跨首片钢箱梁成功吊装，标志着大桥进入上部结构施 工新阶段。 上午9时，现场总指挥发出指令，缆载吊机巨大的钢爪缓缓启动，稳稳嵌入箱梁预设的 吊点。驳船上的"钢铁方舟"稳稳提升。庞然大物悬于半空，在吊机的牵引下，又缓缓地向着 跨中预定的坐标移动。当钢箱梁底部的导向装置与下方结构发出轻微的"咔哒"声响时，首片 梁段稳稳坐落在预定位置上。 "我们还采用了数字孪生系统，来实时监测缆载吊机的应力、变形和吊装姿态，并对风 速、风向等环境因素进行实时监测，确保梁段吊装精度控制在毫米级。"中交二航局双柳长 江大桥项目负责人付望林表示。 武汉双柳长江大桥建成后，武汉新洲到鄂州的行车距离将由一个半小时缩短为5分钟， 有利于加快武汉都市圈一体化发展。同时，项目将打通阳逻国际港到花湖机场、武汉国家航 天产业基地与光谷的快速通道，完善和提升物流枢纽功能，促进"光谷""星谷"联动融合发 展。 见习编辑：冯瀚莹 武汉双柳长江大桥正在进行主跨首片钢箱梁吊装。通讯员黄子珅 摄 新港高速公路武汉双柳长江大桥及接线工程是国家高速公路网 ...

Core Viewpoint - The successful installation of the first steel box girder for the Wuhan Shuangliu Yangtze River Bridge marks a significant advancement in the construction of this major infrastructure project, which is part of the national expressway network and aims to enhance regional connectivity and logistics efficiency [1][4][10]. Group 1: Project Overview - The New Port Expressway Wuhan Shuangliu Yangtze River Bridge is a crucial component of the G9906 Wuhan Metropolitan Circle Ring Road, with a total length of 35.04 kilometers [4]. - The main span of the bridge measures 1430 meters and is 50.5 meters wide, designed for a speed of 120 km/h, featuring an eight-lane dual carriageway, making it the widest steel box girder suspension bridge on the Yangtze River [4]. - The main span consists of 90 girder segments, with the first installed segment measuring 13.0 meters in length, 50.5 meters in width, 4 meters in height, and weighing approximately 298.6 tons [4][7]. Group 2: Construction Techniques - The installation process utilized a digital twin system to monitor the stress, deformation, and positioning of the lifting equipment in real-time, ensuring precision control within millimeter levels [7]. - Environmental factors such as wind speed and direction were also monitored during the lifting process to enhance safety and accuracy [7]. Group 3: Economic and Regional Impact - Upon completion, the bridge will significantly reduce travel time from Xinzhou to Ezhou from one and a half hours to just five minutes, facilitating the integration of the Wuhan metropolitan area [10]. - The project will create a fast transport corridor connecting Yangluo International Port to Ezhou Huahu Airport and the Wuhan National Aerospace Industry Base, thereby improving logistics hub functionality and promoting the integrated development of "Optics Valley" and "Star Valley" [10].

6月4日，汉南长江大桥北岸锚碇沉井施工现场，80多名工人正在进行锚碇沉井下沉作 业，重达数百吨的预制钢筋部品通过巨型吊机，如积木般精准嵌入深达43米的沉井内。 建设中的汉南长江大桥 "这是世界公路工程第一大沉井，面积相当于14个篮球场，有15层楼高。"武汉交投汉南 桥项目公司工程部部长胡志红说，汉南长江大桥锚碇采用整体式沉井基础，面积近6000平方 米，首次下沉锚碇重约9.4万吨，沉井采用接高与下沉交替进行，目前已下沉深度5米。 编辑：李智恒 胡志红介绍，为抢抓主汛期来临前黄金建设期，工程日夜施工，采用大型沉井装配化建 造技术，在预制厂内将隔墙分块预制成半成品，现场逐块组拼成形，提升工业化建造水平。 目前，大桥两岸沉井均已启动下沉，南岸锚碇沉井下沉深度已达15.8米，计划年底全部完 工。 据介绍，汉南长江大桥及接线工程预计2027年建成通车，将打通武汉都市圈环线高速， 串起武汉、孝感、咸宁、鄂州、黄冈等城市，打造一小时通勤圈，推动武汉都市圈同城化进 程。 锚碇是一座大桥的"基石"，也是"定海神针"，由沉井和锚体组成，承担着固定桥梁缆索 的巨大拉力，沉井内有36个孔，结构类似方形蜂窝煤。 目前，武汉在建的第12 ...
