| 摘 要： | 从已有的应力平衡方程、水连续性方程、能量守恒方程和弹塑性矩阵入手,使用 Galerkin 方法将各控制方程分别在空间域和时间域进行离散,初步开发出了一个用于分析饱和岩土介质中热-水-应力耦合弹塑性问题的二维有限元程序,并通过 2 个算例进行了应用尝试。

| Abstract: | Firstly the momentum equilibrium equation, the continuity equation for water, the energy balance equation and the elastoplastic matrix are established. Secondly by using the Galerkin method all the governing equations are discretized in the space domain and time domain respectively, then a two dimensional FEM code for coupled thermo-hydro-mechanical elastoplastic analysis of saturated porous media is developed tentatively. Through two computational examples the use try of the code is made. |
