OSLO RAIL TUNNEL TURNS TO FREEZING TO SAVE HISTORIC BUILDINGS

The article discusses construction problems encountered in the driving of a 3.6 km long railway tunnel beneath the city of Oslo. Varying ground conditions, historical buildings and heavy traffic were some of the problems confronting the contractors. Ground freezing techniques were used at one section where a rock depression was encountered making blasting impossible. To establish the frozen zone, locations for pipes carrying the freezing liquid were drilled from an existing tunnel during night time operations. Details of freezing equipment and techniques used are given. After freezing, tunnel blasting operations were carried out and cast-in-situ concrete lining placed. The concrete lining was increased in thickness to avoid problems of cracking near to the frozen rock face.
