Application and Research on the Model of Saturated-Unsaturated Porous Material Coupling Hydro-Thermal-Mechanical Process

摘要：

The study of hydro-thermal-mechanical process coupling in unsaturated porous material is very important due to its close relationship with environmental geomechanics engineering.The model established upon the deforming porous material mechanics is analyzed in this study.This model takes into consideration the phase change and heat effects.Four balance equations associated with four state variables including gas pressure,capillary pressure,temperature and displacement are imposed.Besides,the governing equations are discretized with the selected Galerkin method and the program has been developed.Using this program simulates two experiments,which representing the saturated non-isothermal consolidation phenomenon and rainfall experiment respectively.The results revealed that this multi-field coupled model is a useful tool to analyze the porous material that coupled with hydro-thermal-mechanical process.
