Research conclusions:(1) By using the thermal probe group, the temperature of the surrounding wall will be significantly reduced within its sphere of influence, the strength of the surrounding wall of permafrost will be enhanced, and the top limit of the permafrost will be raised to form a waterproof curtain on the tunnel ceiling for reducing the frost heaving force on the tunnel supporting structure.(2)The water above frozen layer can’t infiltrate into the tunnel structure and the refreezing time will be reduced from 3 to 5 freezing and thawing cycles to 1 cycle. In this way, the problem of the freeze-thawing damage to the supporting structure in the portal section can be solved.(3)This technology has features of lower engineering cost and more convenience in terms of installing and monitoring. (4)This research achievement can be used for the disease control and treatment of the shallow section of tunnel in the permafrost area.
