瑞士政府为增加该国货运通行能力,计划开辟一条连接南北欧洲的铁路新干线。在这条干线中,沿瑞士南部阿尔卑斯山脉拟建的深层圣哥大铁路隧道,将成为世界上最深的运输隧道。隧道位于圣哥大峰,全长49km,最大覆盖层厚度为2000m。初步方案采用设置双向车道、直径12m的单孔隧洞作为运输隧道,同时在其旁边平行布置一条直径7m的服务隧道。
The Swiss government plans to open up a new railway line linking southern and northern Europe in order to increase its cargo capacity. In this route, the deep Saint-Germain-Great railway tunnel to be built along the southern Swiss Alps will become the deepest transport tunnel in the world. The tunnel is located in Saint Gertrude, a total length of 49km, the maximum thickness of the cover is 2000m. The initial program uses a two-way lane, a single-hole tunnel with a diameter of 12m as a transport tunnel, and a service tunnel of 7m in diameter parallel to the tunnel.
