The macro- and micro-behaviors of a granular soil medium may change due to chemical or physical processes such as particle dissolution, cementation and desiccation. The purpose of this study is to investigate the behaviors of soluble granular mixtures during particle dissolution. Numerical simulations were carried out by using the discrete element method. Soluble mixtures are represented by assemblies of insoluble particles and soluble particles, with the different soluble particle contents. The particle dissolution process is implemented by reducing sizes of the soluble particles. The results of the simulations show that the vertical displacements rapidly increase and converge to stable values during particles dissolution, while the porosities still increase until the soluble particles are completely dissolved. The vertical displacements initially converge for the mixtures containing low soluble particle contents. The porosities and vertical displacements increase with the increasing of soluble particle. The microscopic views show that the fabrics of the mixtures change to more anisotropy packing states. The higher the soluble particle content the larger the changes in the fabric. The microscopic views provide good evidence for the evolution of the vertical displacements. The results demonstrate that the particle dissolution greatly affects to the soluble mixtures.
