| 摘 要： | 基于增量迭代法和粘弹塑性问题的衣构关系,本文导出了粘弹塑性大变形问题的有限元方程,编制了相应的分析程序。通过对采地下巷道围岩进行粘弹塑性大变形分析表明,其结果与实测结果吻合较好。

| Abstract: | Based on the incremental iteration and the constitutive. equation of visco-elastoplastic problem, the finite-element, equation of visco-elastoplastic large-deformation problem has been derived, and the corresponding analytic program also worked out. The analysis on the surrounding rock of some underground opening shows that the computation is well coincident with the data measured in-situ. |
