The current stress level in the ground has important effects on the deformation and strength characteristics of soils and on the performance of the engineered geosystems. The value of ko=σ'h/σ'v reflects soil type and formation history. In particular, post-depositional physical and chemical alterations not only affect the mechanical and chemical properties of soils [1], but may alter the values of ko as well. The purpose of this study is to explore the evolution of ko during mineral dissolution using a combination of experimental, analytical and numerical methods.
