- •
A TPCT group is used to control the ground temperature for a shallow tunnel section.
- •
A composite heat transfer model is developed for the tunnel with a TPCT group.
- •
The TPCT group can cool down the soil layers in the shallow tunnel section.
- •
The research could provide help for applications of TPCTs in other cold regions engineering.
