英文摘要：

Based on the governing equation of the soil consolidation with consideration of the effect of thermo- osmosis and coupling, a method for solving the consolidation of a cylinder of saturated porous medium with infinite length is established. Fourier, Laplace Transforms and their inverse transformations are used to obtain the analytical solution of the thermal consolidation. Then for the problem of the heat source consolidation of a cylinder with infinite length, approximate solutions of the soil＇s temperature and the pore pressure around the cylinder under the non-isothermal condition are obtained. The influence of the heat permeability coefficient and the consolidation coefficient of the soil consolidation under the action of the temperature is analyzed.
