A transient heat transfer model of the soil temperature field around a vertical U-tube of ground source heat pump was established. The numerical simulation was obtained by using the implied finite difference method. By making the simulation of cooling and heating mode, the change rules of the soil temperature along the radial direction, the change rules of the exit water temperature of the buried pipe and the thermal influencing radius in the vertical multi-pipe were obtained.
