摘要：
The Oslofjord sub sea tunnel runs through a rock depression zone filled with glacifluvial material. The zone is highly permeable with a hydrostatic water pressure of 120 in. Artificial ground freezing was undertaken to get through this zone in a controllable and safe manner. The design of the frozen structure was verified with 3D finite element analysis. New experiences were gained within mechanical behaviour of frozen soil with saline pore water, drilling, blasting, and casting procedure of the concrete lining.
