Simulation of generic tunnels for the high speed railway with respect to cold and ice (English)
Abstract [sv]

Projektet syftar till att beräkna temperaturer och isbildning i tunnlarna på de planerade höghastighetsbanorna. Det främsta användningsområdet för resultaten är som bakgrund för dimensionering av betonglining och bakomliggande isolering. Följande storheter har beräknats för ett stort antal typtunnlar som föreskrivits av Trafikverket:

• köldmängdens fördelning längs tunneln

• temperaturdifferensen över betongliningen

• ismängd innanför betongliningen längs tunneln

• frostinträngningsdjup, dvs. hur långt från mynningarna som tunnelväggen fryser.

Samtliga typtunnlar i studien har samma oisolerade väggkonstruktion.

Abstract [en]

This project aims to calculate temperatures and ice formation in the tunnels needed for the planned Swedish high-speed rail. The primary use of the results is as a background to produce guidelines for the dimensioning of concrete lining and insulation in tunnel walls. The following quantities have been calculated for a large number of generic tunnels prescribed by the Swedish Transport Administration:

• the frost index distribution along the tunnel

• the temperature difference across the concrete lining

• the frost penetration, i.e. how far, measured from the tunnel mouth, the tunnel wall experiences negative temperature

• the amount of ice behind the lining.

All generic tunnels have the same uninsulated wall construction.
