摘要
在推证多孔介质三场耦合数学模型微分控制方程的基础上，系统地推导了６结点三角形单元的固液两相介质 的温度场、变形场、渗流场三场耦合问题的有限元格式，开发了我国的三场耦合数值分析软件ＣＤＳＴ，并对该程序的 可靠性及分析精度进行了验证，最后运用该软件对一工程实例进行了三场耦合有限元分析。
Based on the newly reformulated governing equations for the fully coupled thermo-hydro-mechanic behavior of the porous media, a FEM formulation with six-node triangle element to solve the coupled thermo-hydro-mechanic equation system is derived and the related software CDST is also developed and verified. Finally, a FEM analysis with the developed software CDST for the coupled three-fields of an engineering problem is illustrated in detail.
