深汕高铁建设近日实现多项重要突破。龙岗隧道宝荷盾构段的盾构机"龙岗1号"完成下穿深圳地铁14号线，这是全线首例超大直径高速铁路盾构隧道近距离下穿快速地铁运营线，攻克了全线核心高风险施工节点1。今年以来，项目进展加快，8月底三角山隧道顺利贯通，成为全线首座贯通的5000米以上隧道1，此外还实现了多座大直径盾构机下穿河流等重要阶段性成果1。
深汕高铁设计速度为每小时350公里，正线全长125.5公里，其中深圳段69.5公里、惠州段56公里1。全线桥隧比高达92.6%，沿线设6座车站、18座双线隧道、37座大中桥梁1。按照建设总工期5年的计划，项目预计于2027年建成通车1。届时，深圳中心城区至深汕特别合作区的通行时间将压缩至30分钟1。
The Shenzhen-Shanwei High-Speed Railway project has achieved several significant construction milestones recently. 1 The shield tunneling machine "Longgang No. 1" in the Bahe section of Longgang Tunnel successfully completed an undercrossing of Shenzhen Metro Line 14, marking the first instance of a large-diameter high-speed railway shield tunnel passing in close proximity beneath an operational rapid transit line on the entire route. 1 This breakthrough addresses one of the project's most critical high-risk construction nodes. 1
Additional progress includes the breakthrough completion of Sanjiaoshan Tunnel in late August, which became the first tunnel exceeding 5,000 meters in length to be fully excavated on the entire line. 1 The railway is designed with an operational speed of 350 kilometers per hour and spans 125.5 kilometers in total length, with 92.6 percent comprising bridges and tunnels. 1 The project is divided into two sections: 69.5 kilometers in Shenzhen and 56 kilometers in Huizhou. 1 The construction timeline spans five years, with completion targeted for 2027. 1
Upon completion, the railway will significantly reduce travel time between Shenzhen's central district and the Shenzhen-Shanwei Special Cooperation Zone to approximately 30 minutes. 1 The line will feature six stations, 18 double-track tunnels, and 37 major and medium-sized bridges. 1
