The modeling of swelling behavior is a necessary step to evaluate swelling minerals as sealing materials and to design an underground waste repository. The purpose of this study is to construct a mathematical model to describe the swelling behaviors of clay minerals and to develop a new FEM program in which a hydromechanically coupled procedure is incorporated to analyze stresses, displacements, uptakes, and volume expansions/pressure build-ups in swelling geological materials.
