车流穿梭的背后，一套覆盖"海陆空"的智慧运维系统在同步运转。在粤港海洋基础设施联合实验室的支 撑下，港珠澳大桥数字化工程建设与运维全面推进，团队通过数字孪生等技术构建了一座与大桥1：1对 应的"数字大桥"，依托实时数据采集，精准反映港珠澳大桥的细微变化，全天候守护港珠澳大桥的结构 健康。 港珠澳大桥智慧运维的背后，大湾区的科创协同也在不断走深。依托粤港海洋基础设施联合实验室，粤 港双方的技术优势将进一步整合，共同推动港珠澳大桥智能化运维成果迭代，为大桥安全运营持续提供 技术支撑。 "海陆空"全域覆盖 春运期间，港珠澳大桥迎来车流、客流双高峰。今年2月2日至2月11日，港珠澳大桥累计车流量约15.82 万车次，同比增长26.51%。 当车流在港珠澳大桥上穿行而过，大桥的数据中心正同步"感知"着这座超级工程的每一处细微脉动。风 速、位移、环境变化，各项数据实时跳动更新，精准映射着实体大桥的实时状态。 自2018年10月开通，这座跨越零丁洋、连接粤港澳的大桥，早已超越物理通道的定义，成为大湾区的经 贸新通道和物流大动脉，让1小时生活圈从蓝图变为现实。 港珠澳大桥桥隧全长55千米，对于复杂的服役环境，精准感知结构状态 ...

Core Viewpoint - The Pingtan Strait Rail-Road Bridge, a significant engineering project, has transformed transportation in the region since its opening in 2020, facilitating economic growth and connectivity in northeastern Fujian province [1][3]. Group 1: Engineering and Innovation - The bridge, spanning 16.34 kilometers, operates in extreme weather conditions, with over 300 days of winds exceeding level 6 annually [1]. - The bridge's maintenance team has adopted advanced underwater robotic technology, significantly improving the accuracy and efficiency of inspections, with a detection error margin of ±2% for concrete strength [2]. Group 2: Economic Impact - The bridge has reduced travel time between Fuzhou and Pingtan to half an hour, creating a "half-hour living circle" that enhances the flow of construction resources by three times [3]. - The infrastructure has attracted numerous central state-owned enterprises to establish regional headquarters, leading to the formation of an engineering industry cluster with an annual output value exceeding 8 billion yuan [3]. Group 3: Social Transformation - The bridge has fundamentally changed the transportation dynamics for island residents, eliminating previous difficulties in accessing the main island, particularly during adverse weather conditions [3]. - The completion of the bridge has spurred the growth of local industries such as hospitality and marine aquaculture, significantly increasing tourist traffic [3].
