【 摘 要 】

This paper presents an overview of analysis the mechanical behavior of argillite; FE simulation uses an elastoplastic model that has been developed based on a competition between an anisotropic ductile behavior (direction of the subsidence's strain) and an anisotropic semi-fragile behavior (direction of the extension's strain), a nonlinear damage cumulative is considered to evaluate the creation of discontinuities due to material degradation. FE results matches well with the experimental results on the core samples. Consequently, the model shows that it can be applied to evaluate the retaining walls of future storage structures of nuclear waste.
