The long-term (one year) influence of hydration heat released by cement during solidification on the ground temperature around the energy piles is discussed in this paper. The one-dimensional multi-layer medium model and the Green's function method are used to obtain the analytical solution of the ground temperature field. The influences of several factors on the magnitude of the temperature rise are discussed. The results show that the pile diameter has the most significant effect on the
