金塘海底隧道是甬舟铁路控制性工程，位于东海海域宁波与舟山之间的金塘水道下方，西起宁波市北仑区，东至舟山市金塘镇，全长16.18公里，其中采用盾构法施工区段长11.21公里，是世界最长海底高铁隧道。
其中舟山段由盾构机“定海号”掘进，共需要完成3135环约6.3公里，计划最终与宁波段隧道的“甬舟号”在海底实现径向错位小于20毫米的海底盾构高精度对接。
甬舟铁路是国家《中长期铁路网规划(2016—2030年)》重大项目，线路全长76.4公里，设计时速250公里。
项目建成运营后，将结束舟山群岛不通铁路的历史，长三角惟一不通高铁的地级市舟山市将接入全国铁路网，对实现宁波舟山同城化发展，加快两地融入共建“一带一路”和长江经济带发展，打造“轨道上的长三角”，助力长三角一体化高质量发展等具有重要意义。(Welcome back. It's good to see you. Click below to log in to the rewards program at your property.完)
