| 摘 要： | 通过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。通过一维固结问题的有限元解与太沙基解析解的对比，以及对一个简化的核废料地下处置的热-水-应力耦合问题的数值计算，验证了本程序的正确性。

| Abstract: | Based on equations of stress equilibrium, hydraulic continuity and energy conservation as well as the elasto-plastic matrix, using Galerkin method, a 2D finite element program has been developed for analyzing the coupled thermo-hydro-mechanical elasto-plastic problems of saturated rock media. By comparing the solutions from finite element analysis and Taskey analysis for 1D consolidation problem and simplified numerical calculation of coupled thermo-hydro-mechanical problem for the underground facility of nuclear waste treatment, the correctness of this program has been verified. |
