Abstract

Thermo-mechanical coupling is a key research topic in geotechnical engineering today for solving thermal geotechnical engineering problems, including underground energy engineering projects, radioactive waste disposal, oil transport and thermal pipelines, and thermal soft ground stabilization methods. The classical principle of the effective stress in soil mechanics describes the pressure distribution between the soil skeleton and the pore fluid for saturated soil. However, the pressure distribution and its changes between the soil skeleton and the pore water with thermal-mechanical coupling have rarely been reported. This study combines the macroscopic thermal response of the soil consolidation with the classical effective stress principle to analyze the influence of heating on the soil skeleton and the pore water to develop an effective stress and pore pressure prediction formula that includes the influence of temperature. The effective stress principle considering the temperature effect is used to analyze the effective stress and pore pressure distributions for various displacement and drainage boundary conditions. The results show that the thermo-mechanical coupling affects the total stress, the excess pore water pressure and the effective stress in the soil. The temperature stress and the thermal excess pore pressure caused by heating change with time and affect the soil consolidation and compression. The thermal stresses affect the soil stress state and indirectly affect the soil compressibility and strength. The research results can be used to develop thermal consolidation theory and to analyze problems related to thermal geotechnical engineering.
