Abstract: This paper presents the research results of a seepagestress coupling model for the elastic modulus of tailing columns under the action of chemical fluids. Based on the previous research results by others, the effect of change of pH properties of the chemical solutions with time on the elastic modulus of tailing columns is numerically analyzed.
