Based on the comprehensive analysis of subgrade engineering and heating engineering ， it is proposed to use the ground source heat pump technology in the field of subgrade engineering construction. A special ground source heat pump is designed， which has an independent heating unit. It is found that the heating temperature of the device is higher than 50℃， the collecting temperature is lower than -8℃， and the effective heating radius is greater than 1.41m. The designed ground source heat pump device has obvious advantages in the field of subgrade frost heave and is worth popularizing.
