ABSTRACT
Main task in the design and construction of a tailing pond is to ensure that the tailings dam can withstand seismic actions, in an area with high seismic activity, such as Bulgaria. Modern FEM analysis software packages, that can evaluate the seismic stability of such type of structures require as an input parameter the dependencies G = f (γ) and D = f (γ) in the range from 104% to101%. One method to derive with these dependencies in a laboratory conditions is the dynamic triaxial shear. In this article we present, the results from the tests carried out on undisturbed tailings samples taken from different depths (20 to 90m) of “Lyulyakovitza” tailing. The obtained results were evaluated and statistically analyzed in order to derive with the dependencies for G = f (γ) and D = f (γ).
