   Författare :Anna Andrén; Lars-Olof Dahlström; Erling Nordlund; Lars O Ericsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tunnel; frost penetration; ice formation; freeze-thaw test; frost shattering; temperature measurement; maintenance; degradation of rock and shotcrete; cold climate; Tunnel; köldinträngning; isbildning; frystester; frostsprängning; temperaturmätning; underhåll; nedbrytning av berg och sprutbetong; kallt klimat; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : Water in the surrounding rock mass flows into the tunnel via naturally occurring joints and via cracks caused by the blasting used to excavate the tunnel. The most common method in Sweden to reduce or prevent leakage problems are first and foremost the use of grouting. LÄS MER
