Modeling of a nuclear waste disposal: Numerical and practical aspects

Autor: S. Granet, D. Le Boulch, C. Chavant

Publikováno v: Poromechanics II ISBN: 9781003078807

Radioactive waste management is an important environmental issue today. One of the possible solutions is the deep geological underground disposal. In order to improve our model and to have an expert appraisement, especially concerning the hydro-mecha

Numerical implementation of a new rheological law for argilites

Autor: Philippe Kolmayer, C Chavant, Roméo Fernandes

Publikováno v: Applied Clay Science. 26:499-510

This article presents the numerical implementation of an elastoplastic behavior model suitable for estimating the damage produced when excavating galleries in deep argilite layers. The main rheological features of the model are related to post-peak b

Poroplastic modelling of the excavation and ventilation of a deep cavity

Autor: F. Homand, A. Blaisonneau, Albert Giraud, C. Chavant, Dashnor Hoxha

Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 28:339-364

A plastic deviatoric model with hardening is developed on the basis of geomechanical tests performed in the saturated case on low permeable porous material such as argillite. This model is a generalized Mohr–Coulomb plastic criterion combined with

International audience; In order to increase the accuracy and the stability of a scheme dedicated to the approximation of diffusion operators on any type of grids, we propose a method which locally reduces the curvature of the discrete solution where

Thermo-Hydro-Mechanical Numerical Modelling: Application to a Geological Nuclear Waste Disposal

Autor: S. Granet, C. Chavant, R. Fernandes

Publikováno v: Computer Applications In Geotechnical Engineering.

1. Abstract The production of nuclear energy is facing at the present time to the issue of the management of radioactive waste. A great deal of attention is focused on the feasibility of deep geological underground disposal. Consequently, deep knowle
