中国成功将一条长达16公里的高速铁路隧道建设于海底，这一工程奇迹指的是深江铁路（深圳至江门）的关键控制性工程——珠江口隧道。该隧道穿越珠江入海口海域，最大埋深达106米，是目前中国在建埋深最深、水压最高的海底高铁隧道。施工团队采用世界领先的盾构技术，克服了高水压、强腐蚀、复杂地质等多重挑战，确保隧道结构安全与长期稳定。该项目不仅体现了中国在超长海底隧道建设领域的技术突破，也为未来跨海交通基础设施提供了宝贵经验。建成后，深江铁路将大幅缩短粤港澳大湾区主要城市间的通行时间，强化区域一体化发展，进一步推动经济协同与人员往来。这条海底高铁隧道的建设，标志着中国基建能力迈上新台阶，也彰显了其在全球重大工程领域的领先地位。
China has successfully constructed a 16-kilometer high-speed rail tunnel beneath the seabed—an engineering marvel known as the Pearl River Estuary Tunnel, a key section of the Shenzhen–Jiangmen Railway. This tunnel passes under the Pearl River estuary, reaching a maximum depth of 106 meters below sea level, making it the deepest and highest-water-pressure underwater high-speed rail tunnel currently under construction in China. Engineers employed world-leading tunnel boring machines (TBMs) to overcome extreme challenges including intense water pressure, corrosive seawater, and complex geological conditions, ensuring structural integrity and long-term stability. This project not only demonstrates China’s technological breakthroughs in ultra-long underwater tunneling but also provides valuable experience for future cross-sea transportation infrastructure. Once completed, the Shenzhen–Jiangmen Railway will significantly reduce travel times between major cities in the Guangdong–Hong Kong–Macao Greater Bay Area, enhancing regional integration and boosting economic collaboration and mobility. The construction of this underwater high-speed rail tunnel marks a new milestone in China’s infrastructure capabilities and underscores its global leadership in large-scale engineering projects.
