In this paper, stability of soil foundation is simulated by means of analytical limit analysis in which generalized viscoplasticity is introduced by augmented Lagrangian technique.
多重势面模型直接从数学原理出发建立本构关系,避开了传统塑性理论中屈服面的概念,为研究岩土工程材料本构模型提供了新的思路。
The multi-potential surface model in strain space is more practical, since its parameters are easy to be determined, and the program based on the model is easy to be developed.
