在参与高放射性核废料地质处置库的缓冲层饱和过程的诸多因素中,初始的水头、渗透系数和饱和度最为关键。作者使用THM耦合问题的二维有限元方法分析了以上三个因素对缓冲层饱和过程的影响。由计算结果可知,初始的水头、渗透系数和饱和度的数值越大,缓冲材料达到饱和的时间越快,反之亦然。
Among a lot of factors participating in the saturation progress of buffer material in geological disposal for high level radioactive nuclear waste, the initial head, permeability and saturation degree are the most keys, The author uses a 2 D FEM code for coupled thermohydromechanical phenomena to analyze the influence of the three factors mentioned above on the saturation progress of buffer material. From the results it is known that the bigger of the values of the initial head, permeability and saturation degree is, the faster of the saturation velocity is; and vice versa.
