Research on Thermoelastic Dynamic Problems for Three Dimensional Porous Media

Wang Jianxing(College of Arch., North China Univ. of Tech., 100041, Beijing, China)  
Based on Biot Theory and taking into account the effects of transient thermal loading or thermo-elasticity, the basic equations for three dimensional porous media are presented, and four types of boundary of porous media (Phrear-atos-1 ~ 4)under the action of transient thermal loading or thermo-elasticity are discussed. The analysis shows that the thermal loading has an important effect on the performance of the porous media. From the mathematical point of view, the form of the boundary element method for the macroscopic consolidation of Biot Theory under transient thermal loading is deducted, and integral representation of the displacement fields under pore pressure is obtained. Finally, the results obtained by using the methods are given.
