Abstract In order to prevent the degradation of permafrost under subgrade in permafrost area，and test the refrigeration effect of the developed solar driven compression refrigeration apparatus，the field test was carried out in Qinghai Permafrost Research and Observation Base of the Ministry of Transportation. The results show that the apparatus can continuously cool the soil in cold season and warm season. The refrigeration mode can affect the distribution of refrigeration temperature along the pipe wall，and the bottom-up refrigeration mode is more effective to cool the permafrost subgrade. The average refrigeration temperature of the apparatus is positively correlated with the ambient temperature. The average refrigeration temperature in cold season is lower，the lowest is －7.97 ℃，and the highest is －3.98 ℃ in warm season. When the average refrigeration temperature is lower than －6.5 ℃，the refrigeration capacity of the apparatus is greater than that of the soil，the soil cold storage capacity increases and the ground temperature decreases，on the contrary，the ground temperature increases. The refrigeration radius of the apparatus is affected by the ambient temperature，and the refrigeration radius is 1.95‐2.61 m. The apparatus can be arranged on both sides according to the distance of 4‐5 m in subgrade engineering. To sum up，the solar driven compression refrigeration apparatus can be effectively applied to the temperature control of permafrost subgrade and can guarantee the reliability and safety of permafrost subgrade in a long term.

Key words： soil mechanics permafrost degradation subgrade photovoltaic generation compression refrigeration refrigeration temperature
