Frozen soil roadbed structure

The invention discloses a frozen soil roadbed structure which comprises a solar power generation system, a thermal cycle temperature control system and a frozen soil roadbed. The solar power generation system is electrically connected with the thermal cycle temperature control system and used for providing electric energy for the thermal cycle temperature control system. The thermal cycle temperature control system comprises a compressor, an electronic control valve, a condenser, an upper plane type copper pipe, a one-way valve combination, a throttling valve and a lower plane type copper pipe. The frozen soil roadbed is sequentially composed of a pavement structure layer, a roadbed body and a replacing and filling layer, the upper plane type copper pipe is arranged at the bottom of the pavement structure layer, and the lower plane type copper pipe is arranged at the bottom of the replacing and filling layer. According to the embodiment, the solar power generation system is used for conducting green heat regu
